**Typesense** has established itself as a powerful open-source search engine that gives developers exceptional control over their search implementation. With its flexible query-time configuration and resource-based pricing model, it offers an alternative to both Elasticsearch's complexity and Algolia's usage-based costs.

To create this **Typesense review**, I've analyzed the platform extensively. I believe it's the ideal choice if:

* You need flexible query-time configuration over your search parameters  
* You prefer resource-based pricing rather than per-document costs  
* You want detailed control over ranking and relevancy  
* You're comfortable with more initial configuration for greater flexibility  
* You need a self-hostable solution with strong API capabilities

However, Typesense might *not* be the best choice if:

* You want the simplest possible setup with minimal configuration  
* You prefer the flexibility of choosing between subscription tiers or resource-based pricing  
* You need to get a search implementation running in minutes  
* You're looking for more opinionated defaults that work great out-of-the-box  
* You want a gentler learning curve with extensive getting-started resources

In this case, you should consider **Meilisearch**: an open-source search engine that prioritizes simplicity and developer experience above all else, offering a smoother onboarding experience and faster time-to-production while maintaining excellent search performance.

*Because of that, I've included a detailed look at Meilisearch later in this Typesense review, as an alternative for teams seeking simplicity over configurability.*

## What is Typesense?

**Typesense** was [co-founded by Jason Bosco and Kishore Nallan](https://www.flagsmith.com/podcast/typesense), with the idea originating in 2015 as a nights-and-weekends project. 

![1 - What is Typesense.png](https://unable-actionable-car.media.strapiapp.com/1_What_is_Typesense_1457a5276e.png)

The founders were frustrated with Elasticsearch's complexity and wanted to democratize search by creating a lightweight, high-performance engine that would be intuitive to use out of the box.

The first open-source version launched in 2018, and by 2020, both founders had left their full-time jobs to focus on Typesense after a successful Hacker News post generated significant interest. The company has remained self-funded and revenue-funded, deliberately avoiding venture capital to maintain a sustainable approach.

[Built in C++ for maximum performance](https://github.com/typesense/typesense), Typesense typically delivers search results in under 50 milliseconds while handling typos automatically (enabled by default) and supporting configurable synonyms and complex filtering. The platform offers both keyword and vector search capabilities, making it suitable for traditional search as well as AI-powered semantic search applications.

Today, Typesense serves developers and businesses who need a powerful yet manageable alternative to Elasticsearch's operational overhead or Algolia's usage-based pricing. It's particularly valued by teams who want control over their search infrastructure without sacrificing performance or relevance.

## Typesense Review: How it Works & Key Features

### Query-Time Flexibility and Configuration

**Typesense's** standout feature is its ability to configure search parameters at query time rather than index creation. 

Unlike platforms that require separate indices for different sort orders or configurations, Typesense allows dynamic adjustment of fields to search, facet, and rank through API parameters.

This flexibility extends to sorting, where a single index can provide results sorted by price ascending, price descending, or relevance without creating duplicate indices. The platform calculates [facet counts using three strategies](https://typesense.org/docs/guide/faqs.html#faceting): exhaustive for exact counts on smaller sets, top\_values using reverse indexing for large sets, and automatic selection based on the query.

![2 - Query-Time Flexibility and Configuration.png](https://unable-actionable-car.media.strapiapp.com/2_Query_Time_Flexibility_and_Configuration_5d05eb3706.png)
Source: [*Typesense*](https://typesense.org/docs/guide/faqs.html#faceting)

Search-time parameter changes update automatically without re-indexing, significantly reducing operational overhead for certain configuration changes. However, schema modifications and structural changes still require recreating collections and re-indexing data.

### Search and Ranking Capabilities

The search functionality uses a [tie-breaking algorithm](https://typesense.org/docs/guide/ranking-and-relevance.html) with customizable ranking rules applied sequentially. Default rules include frequency of overlapping tokens, edit distance for typo tolerance, and custom field-based sorting. Documents with exact matches are prioritized, though this behavior can be disabled.

The system handles up to two typos for longer words by default, with configurable thresholds based on word length. [Synonyms can be one-way or multi-way](https://typesense.org/docs/27.0/api/synonyms.html), allowing terms like "blazer," "coat," and "jacket" to be treated as equivalent.

[Natural Language Search capabilities](https://typesense.org/docs/guide/natural-language-search.html) leverage large language models to analyze conversational queries into structured search parameters. When enabled, queries are sent to configured LLMs like OpenAI's GPT or Google's Gemini, which translate them into search terms, filters, and sorting instructions.

Source: [*Typesense*](https://www.youtube.com/watch?v=xyXccgMqBow&t=1s)

### Data Management and Indexing

[Collections in **Typesense**](https://typesense.org/docs/26.0/api/collections.html) function like database tables, containing documents with defined schemas. The platform supports flexible schemas through auto-schema detection, allowing fields to be automatically detected and typed, though new documents are adjusted to match the inferred types.

Real-time indexing ensures new or updated documents become searchable immediately. The system uses [RocksDB for storage](https://deepwiki.com/typesense/typesense/5.2-schema-definition-and-field-management), creating multiple inverted indexes to optimize various search features. Text processing and tokenization handle segmentation and normalization automatically.

The platform provides [idempotent endpoints for document management](https://typesense.org/docs/26.0/api/documents.html). Adding a document with an existing primary key replaces the entire document, while partial updates modify only specified fields. Bulk operations through the import API significantly improve performance for large-scale data changes.

### API Architecture and Access Control

**Typesense's** [REST-ful API uses a comprehensive key-based security model](https://typesense.org/docs/guide/data-access-control.html). 

When protected by a master key, all routes except /health require authentication. The system automatically generates a Default Admin API key upon initialization.

[Scoped API keys](https://typesense.org/docs/28.0/api/api-keys.html) enable multi-tenancy by embedding search parameters within HMAC-digested tokens. These keys ensure users can only access their permitted data without the ability to override filters. The API supports fine-grained permissions controlling access per collection, per action, and even per field.

Integration options include [official client libraries](https://typesense.org/docs/guide/installing-a-client.html) for JavaScript, Python, PHP, and Ruby, plus community-maintained libraries for Go, Java, .NET, and other languages. The platform also provides UI components like the [InstantSearch.js adapter](https://typesense.org/docs/guide/migrating-from-algolia.html) for seamless migration from Algolia.

## Where Typesense Falls Short

While Typesense excels at providing flexibility and control, several considerations become apparent for teams prioritizing simplicity and rapid deployment.

**Configuration Complexity:** The platform's strength in customization can become a challenge for simple use cases. Teams wanting basic search functionality must navigate extensive configuration options that may be unnecessary for their needs. The flexibility that allows query-time parameter adjustment requires understanding numerous settings and their interactions.

**Pricing Model Considerations:** While resource-based pricing offers advantages for certain workloads, it requires more calculation than fixed-tier models. The [pay-per-hour cluster pricing](https://cloud.typesense.org/pricing/calculator) (starting from around $7 per month for basic configurations) makes cost prediction dependent on understanding your resource requirements. Unlike platforms that offer both subscription and resource-based options, Typesense's single pricing approach may not suit all budget planning preferences.

**Documentation and Onboarding:** The platform assumes technical proficiency, with documentation targeting developers comfortable with distributed systems and search concepts. Teams without dedicated search expertise may need more time for initial setup, from determining appropriate memory allocation to configuring ranking rules effectively.

These considerations reflect Typesense's optimization for flexibility and control. For teams that value quick deployment, flexible pricing options, and minimal configuration, these constraints may influence their platform choice.

## Top Typesense Alternative for Simplicity: Meilisearch

**Meilisearch** takes a different approach to search by prioritizing developer experience and simplicity. 

![5 - Top Typesense Alternative for Simplicity.png](https://unable-actionable-car.media.strapiapp.com/5_Top_Typesense_Alternative_for_Simplicity_8619e9d308.png)

[Founded in 2018](https://techcrunch.com/2022/10/10/meilisearch-lands-15m-investment-to-grow-its-search-as-a-service-business/) by Quentin de Quelen, Clément Renault, and Thomas Payet, the platform emerged from frustration with existing search solutions that required extensive configuration to achieve basic functionality.

Where Typesense offers flexibility through configuration, Meilisearch provides excellence through carefully designed defaults that work well for most use cases.

### Zero-Configuration Excellence

**Meilisearch** operates on a ["plug-and-play" philosophy](https://www.meilisearch.com/) where search functionality is optimized from the start. The platform requires no initial configuration for typo tolerance, relevancy ranking, or search-as-you-type functionality. These features are enabled and optimized by default.

Setting up a search experience involves three steps: installing Meilisearch, adding documents, and performing searches. Document addition automatically triggers indexing with tokenization and normalization. The system immediately handles typos, with [one typo allowed for five-character words and two for nine-character words](https://www.meilisearch.com/docs/learn/relevancy/typo_tolerance_settings).

![6 - Zero-Configuration Excellence.png](https://unable-actionable-car.media.strapiapp.com/6_Zero_Configuration_Excellence_0303564d3e.png)
Source: [*Meilisearch*](https://www.meilisearch.com/docs/learn/relevancy/ranking_rules)

The [ranking rules apply automatically](https://www.meilisearch.com/docs/learn/relevancy/ranking_rules) in a reasonable order: matching word count, typo count, word proximity, attribute importance, custom sorting, and exactness. This default configuration delivers relevant results for most applications without adjustments.

### Transparent and Predictable Pricing

**Meilisearch** offers unique flexibility with both subscription-based and resource-based pricing models.

The subscription approach provides [clear pricing tiers](https://www.meilisearch.com/pricing) that make budgeting straightforward: the Build plan starts at $30 per month (including 50,000 searches and 100,000 documents), while the Pro plan at $300 per month includes 250,000 searches and 1,000,000 documents.

![meilisearch-pricing.png](https://unable-actionable-car.media.strapiapp.com/meilisearch_pricing_5986ddaecf.png)

For organizations preferring to pay for actual resource consumption, Meilisearch now offers resource-based pricing as an alternative. 

This dual pricing approach provides unmatched flexibility, allowing teams to choose the model that best fits their usage patterns and budget requirements. Whether you need the predictability of fixed tiers or the scalability of resource-based pricing, Meilisearch adapts to your needs.

[Overage charges are transparent](https://help.meilisearch.com/articles/5542905035-what-happens-if-i-exceed-my-plan-limits): $0.40 per 1,000 additional searches and $0.30 per 1,000 additional documents on the Build plan. This flexibility in pricing models allows teams to optimize costs based on their specific workload characteristics. A 14-day free trial lets teams evaluate the platform with actual workloads before committing.

The [open-source version](https://github.com/meilisearch/meilisearch) remains completely free for self-hosting under the MIT license, with core features available for most use cases (enterprise features like sharding require separate licensing).

### AI-Powered Search Made Simple

**Meilisearch** seamlessly integrates AI capabilities through [automated embedding generation.](https://www.meilisearch.com/docs/learn/ai_powered_search/getting_started_with_ai_search#generate-auto-embeddings) 

![8 - AI-Powered Search Made Simple.png](https://unable-actionable-car.media.strapiapp.com/8_AI_Powered_Search_Made_Simple_9a75c812fb.png)
Source: [*Meilisearch*](https://www.youtube.com/watch?v=0tPsBrmtf3o)

The platform connects directly with [OpenAI, Hugging Face, or any REST-based embedding provider](https://www.meilisearch.com/docs/reference/api/settings). Configuration involves simply providing API keys and selecting models.

Document templates enhance embedding quality by specifying which fields contribute to vector generation. For a movie database, templates like "A movie titled: " provide context for better semantic understanding. The [hybrid search parameter](https://www.meilisearch.com/docs/reference/api/search) allows fine-tuning the balance between keyword and semantic results through a simple ratio setting.

Vector storage, embedding generation, and hybrid ranking happen automatically once configured. Developers don't need to manage separate vector databases or coordinate multiple search systems.

### Developer-First Design Philosophy

Every aspect of **Meilisearch** reflects its commitment to developer experience. 

The RESTful API features clear, predictable endpoints with comprehensive documentation. [Official SDKs](https://meilisearch.dev/docs/learn/resources/sdks) for major languages include .NET, Dart, Go, Java, JavaScript, PHP, Python, Ruby, Rust, and Swift.

The [mini-dashboard](https://github.com/meilisearch/mini-dashboard) provides immediate visual feedback during development. [Search preview, analytics, and index management](https://updates.cloud.meilisearch.com/publications/new-integrated-search-preview-and-revamped-index-settings) are accessible through a clean interface. The platform provides descriptive error messages to aid debugging.

Understanding hybrid search RAG for better AI answers

Elasticsearch pricing: Is it worth the price or consider Meilisearch? October 2025

Modern GenAI systems are built on a [retrieval-augmented generation (RAG)](https://www.meilisearch.com/blog/what-is-rag) foundation. 

RAG comes in many forms and varying levels of complexity. Some are simple and easy to use, while others are focused on scaling to the next level. 

In this guide, we’ll cover:

* What ‘naive’ and ‘advanced’ RAG mean, and how they are different from each other.
* The workings of both, from the most basic to the advanced steps.
* Practical insights into the major differences between the two.
* The best time to use them and their applications in real-world use cases.
* The most common benefits and challenges of each.
* The best practices to evolve from naive RAG to advanced RAG, and how you can use Meilisearch to simplify the process

By the end, you’ll know exactly which RAG setup fits your team’s specific situation and performance requirements.

## What is naive RAG?

Naive RAG is the simplest [type of RAG](https://www.meilisearch.com/blog/rag-types). 

It involves a single retriever fetching relevant documents and passing them to a large language model for generation. It relies on vector similarity search, which in turn relies on embeddings and language models such as OpenAI or Sentence-BERT.

You see naive RAG daily, more than you realize. It’s in prototypes, chatbots, and internal tools designed to optimize latency and simplicity. 

However, it’s not the go-to option for accuracy, unlike advanced RAG. Let’s look at that next.

## What is advanced RAG?

When you want to take RAG to the next level, you arrive at advanced retrieval-augmented generation. It builds on the naive approach by adding more layers of precision and reliability through reranking, query rewriting, and multi-stage retrieval processes. This not only improves the accuracy of the generation but also provides final responses that users enjoy reading.

You can find advanced RAG in production environments where the primary focus is on accuracy and removing hallucinations. This is ideal for specific domains, such as finance or healthcare. 

Now, let’s explore how each RAG system works in practice.

## How does naive RAG work?

Naive RAG follows a simple three-step workflow connecting information retrieval and generation.

![How Naive RAG Works.png](https://unable-actionable-car.media.strapiapp.com/How_Naive_RAG_Works_b6dfc9b788.png)

1. **Indexing:** When indexing, the documents are first chunked into smaller sections. These smaller sections are then converted into vector embeddings through language models. Then, these vectors are stored in a [vector database](https://www.meilisearch.com/blog/what-is-a-vector-database), such as Meilisearch or FAISS.
2. **Retrieval:** Similar to document indexing, a user query is also converted into an embedding. The retriever then finds vectors similar to the query from the database using similarity metrics, such as cosine similarity.
3. **Generation:** For each generation process, the retrieved documents are first linked and fed to a large language model (LLM). From the LLM, a response is generated based on the context provided.

Naive RAG prioritizes speed and simplicity. If you want a basic functionality or RAG deployment, this is the way to go. 

Now, let’s see how advanced RAG works.

## How does advanced RAG work?

Advanced RAG builds upon naive RAG through various optimization layers that enhance retrieval and generation quality.

![How Advanced RAG Works.png](https://unable-actionable-car.media.strapiapp.com/How_Advanced_RAG_Works_1c7c6f976d.png)

1. **Pre-retrieval optimization:** Before retrieval even begins, the system rewrites user queries to capture better what the user actually means. This helps in matching domain-specific terminology and providing additional context.
2. **Multi-stage retrieval:** Instead of just one, advanced RAG has multiple retrievers. They pull results from various sources to cover a broader range of information types. The sources can be databases, vector stores, and even APIs.
3. **Post-retrieval reranking and filtering:** The process of reranking serves as an eliminator for the less relevant responses. It uses LLM scoring to deliver the most appropriate answers. 
4. **Auto-merging and context pruning:** Overlapping or repetitive text is merged, and low-value content is removed before generation.
5. **Response generation:** The final, filtered context is passed to the generation model for coherent, grounded answers.

As you can tell, these added layers serve to fine-tune and improve the generated responses to the users’ liking. 

Let’s take a look at the major differences between these two RAG approaches.

## What is the main difference between naive and advanced RAG?

The main difference between naive RAG and advanced RAG is in precision and control. 

Naive RAG has a single retriever loop, whereas advanced RAG includes multiple layers to generate the most accurate responses. 

Naive RAG is the best choice when you want speed and simplicity, while advanced RAG will serve you the best when it comes to optimizing for a highly accurate and reliable RAG pipeline.

![Naive RAG vs Advanced RAG.png](https://unable-actionable-car.media.strapiapp.com/Naive_RAG_vs_Advanced_RAG_92a2a6ca72.png)

Naive RAG is suitable for quick experiments or internal tools, while advanced RAG is built for enterprise-grade deployments that demand the next level of precision and trust.

## What are the benefits of naive RAG?

For teams that are starting out, there is no better starting point than naive RAG. It can be your first step into experimenting in this domain: 

* **Super simple:** For naive RAG, all you need is a retriever, an embedding model, and a generator. This simplicity makes it ideal for quick deployments or creating a proof of concept.
* **Top-tier speed:** Since there’s minimal pipeline orchestration, the responses from naive RAG are quick and have almost non-existent latency.
* **Easy on the wallet:** Thanks to fewer API calls and pretty much zero reranking layers, it’s budget-friendly.
* **Maintenance isn’t a chore:** Since the architecture is so lightweight, you only need to maintain or tune a limited number of moving parts.
* **Flexible:** The flexibility of naive RAG means it works well in question-answering applications, such as chatbots, where accuracy isn’t a significant issue.

## What are the benefits of advanced RAG?

Advanced RAG provides a detailed level of control that naive RAG could never achieve:

* **A monumental jump in accuracy:** Thanks to extra layers, such as reranking, filtering, and query rewriting, advanced RAG generates responses that meet the user’s needs much better than naive RAG responses.
* **Highly relevant:** Through multi-stage retrieval, advanced RAG ensures that users receive only the most relevant chunks within the desired context. 
* **Scalability on point:** Advanced RAG's modular design was specifically created to support large-scale vector databases and hybrid retrievals. It can handle enterprise workloads with ease.
* **Fewer hallucinations:** Continuous feedback loops and evaluation metrics help improve the quality of responses over time.
* **A ton of flexibility:** Since it handles varied data sources, advanced RAG offers a significant amount of flexibility, allowing it to work without retraining the LLM repeatedly.

In short, advanced RAG is the perfect fit for highly critical AI RAG applications and setups that process complex queries. 

To master RAG and its various types, feel free to [check out our official guide](https://www.meilisearch.com/blog/mastering-rag).

## What are the limitations of naive RAG?

Naive RAG’s simplicity makes it easy to start with, but it limits its ability to scale or deliver consistently accurate results over time:

* **Low precision:** Since it retrieves documents only based on similarity scores, there’s a considerable potential for inaccurate responses.
* **Limited recall:** Naive RAG might even miss relevant information entirely because it lacks an element of reranking or query refinement. 
* **Outdated information:** Since retrieval isn’t dynamically refreshed or filtered, responses might include data that’s irrelevant or stale.
* **Room for hallucinations:** The LLM might misinterpret the retrieved information, which could lead to hallucinations.
* **No feedback mechanism:** The absence of evaluation loops or retraining signals results in no improvement over time. 

These issues make naive RAG best suited for experimentation rather than production environments where precision is required.

## What are the limitations of advanced RAG?

Advanced RAG offers scalability and a trust factor, but it comes with inevitable trade-offs.

* **Extremely high complexity:** The many optimization layers increase advanced RAG’s complexity to a point where considerable engineering effort is required to maintain it.
* **It requires resources:** When handling larger pipelines, advanced RAG requires more computing power, memory, and API calls. These costs can add up over time.
* **Risk of overfitting:** Being overly specific limits how well language models can perform across different data types or industries.
* **Harder to evaluate:** To track retrieval precision and hallucination rates, you need to have complex benchmarking setups in place. 

While advanced RAG addresses many of the weaknesses of naive RAG, it requires significant resources to maintain its optimal state.

## When should you use naive RAG?

Naive RAG is the perfect fit if you want to prototype early-stage LLM applications or test prompts. 

Smaller projects, such as chatbots, internal knowledge bases, or proof-of-concept demos, benefit greatly from the speed and simplicity that naive RAG brings. It is also a good fit when data volume is small and latency must stay low, such as in local or offline use cases.

However, naive RAG’s lightweight design means you have to give up on precision and scalability. 

## When should you use advanced RAG?

Are you working in a domain where there’s simply no compromise on precision and accuracy? Then, advanced RAG is your choice. 

It’s ideal for enterprise-grade systems, customer-facing chatbots, and domain-specific assistants. It’s a particularly good fit for medical knowledge platforms or legal research tools. It’s also perfect for large datasets with hybrid retrieval systems.

## What are common applications of naive RAG?

Naive RAG is used where speed and simplicity are more important than any other factor. Let’s see a few typical applications below:

* **FAQ chatbots:** In FAQ chatbots, naive RAG helps generate quick responses from internal documents without requiring complex reasoning.
* **Internal search tools:** Naive RAG helps teams access relevant snippets from wikis, manuals, or emails using simple embeddings. 
* **Knowledge retrieval systems:** Naive RAG is used in systems that require the quick fetching of facts or short answers from a predefined dataset. 
* **Prototype assistants:** Another everyday use of naive RAG is in prototype assistants that developers like to test before scaling with different RAG models.
* **Customer support portals:** Naive RAG helps surface the most relevant articles or troubleshooting guides without requiring full-text generation.

## What are common applications of advanced RAG?

For high-powered systems that thrive on high accuracy and minimal hallucinations, advanced RAG is the go-to choice: 

* **Enterprise chatbots:** Advanced RAG is used in enterprise chatbots that provide well-researched answers across departments by combining various internal knowledge bases.
* **Legal and compliance assistants:** You’ll find advanced RAG in legal and compliance assistants, where you need accurate retrieval or citation of verified information.
* **Medical research tools:** The medical field can’t compromise on accuracy. Advanced RAG is used to provide insights from clinical studies in medical datasets. 
* **Customer support automation:** Advanced RAG is also used to combine semantic search and retrieval with LLM reasoning to provide detailed responses in customer support.
* **AI research assistants:** Advanced RAG supports data scientists and engineers, especially when they handle repositories and experimental data.

All in all, when the environment is complex or data-heavy and regulated, the advanced RAG framework provides the relevant accuracy and transparency that’s needed.

## How does naive RAG compare to GraphRAG?

The main difference between naive RAG and GraphRAG is that naive RAG treats documents as isolated chunks for retrieval purposes. 

[GraphRAG](https://www.meilisearch.com/blog/graph-rag), on the other hand, connects various entities and relationships within a specific context to provide deeper reasoning and traceability. 

![Naive RAG vs GraphRAG.png](https://unable-actionable-car.media.strapiapp.com/Naive_RAG_vs_Graph_RAG_3fe0dc19be.png)

Now, we’ll move to some examples of advanced RAG techniques.

## Examples of advanced RAG techniques

Advanced RAG has its own set of layers and retrieval techniques that help improve the accuracy and precision of responses. 

Many of these techniques are outlined in our in-depth article on [advanced RAG techniques](https://www.meilisearch.com/blog/rag-techniques):

* **Dynamic chunking:** In this process, the documents are broken into contextually coherent pieces rather than fixed blocks. This provides a significant improvement in retrieval quality, eliminating unnecessary noise.
* **Query rewriting:** This refers to the process of rewriting user input before search, so that the retriever surfaces better-matched context. It can be through synonyms, clarification, or similar. 
* **Reranking and filtering:** After the initial retrieval, results are rescored and low-value items are removed. The only way forward is a high-quality response.
* **Hybrid retrieval:** This type of retrieval gives you broader recall and increased precision, which is particularly useful for mixed-type data.
* **Feedback loops and context distillation:** In naive RAG, there are no feedback loops. In advanced RAG, however, the system logs user outcomes and refines chunks over time to improve response accuracy.

Now, we’ll see how you can evaluate naive and advanced RAG setups.

## How to evaluate naive vs. advanced RAG

To evaluate each of these systems, consider how they perform in terms of accuracy, answer quality, and latency. 

Naive RAG generally scores high on speed and simplicity, whereas advanced RAG prioritizes factual grounding and user trust through re-ranking and improved retrieval layers.

For a detailed explanation of evaluation frameworks and metrics, explore our [RAG evaluation guide](https://www.meilisearch.com/blog/rag-evaluation), which breaks down structured methods to assess retrieval and generation quality.

Next, we’ll look at best practices for upgrading from naive to advanced RAG.

## What are the best practices for moving from naive to advanced RAG?

So, how can you methodically transition from a naive RAG to an advanced RAG system? It’s all about maintaining structure without overcomplicating the stack. 

You can start with the following steps:

1. **Audit your current pipeline:** Identify all latency or accuracy issues before adding a layer of complexity. 
2. **Adopt modular upgrades:** Add updates one step at a time. For instance, start with query rewriting, then reranking, and then hybrid retrieval. Track the progress at each step.
3. **Implement continuous evaluation:** Ensure that you keep track of hallucination rates, accuracy, and latency. 
4. **Optimize data and chunking:** Refine document splitting and embedding quality.

## Choosing the right approach in the naive RAG vs. advanced RAG journey

Naive RAG is for teams that are just starting with experimentation and want to test the RAG waters before moving to full-scale deployments. 

Advanced RAG serves better in accuracy-critical domains and large-scale deployments. 

The right choice depends on your goals. If your focus is on testing and agility, start with a naive approach. If your product requires precision, resilience, and scalability, consider adopting advanced RAG techniques.

Naive RAG vs. advanced RAG: What are the differences?

Elasticsearch review: Why developers are choosing Meilisearch for simplicity in 2025

I’ve always loved coding, from the quiet flow and small wins to the feeling of seeing something come alive on the screen.

Yet as Melisearch grew and I fully stepped into my role as co-founder and CEO, those moments became rare. You know how it is: your days fill up with calls, emails, and strategy meetings. The deeper you get into running the company, the further you drift from the keyboard.

Then I discovered vibe coding, and for the first time in years, I felt like I had time to build again – quickly, playfully, almost effortlessly.

Essentially, you describe what you want in a prompt, using natural language, and an AI writes the code for you. You don’t analyze the code line by line. You just follow the flow. You chase the result. You chase the vibe.

Almost a year in, I can tell you this: *vibe coding is addictive*. It feels like magic, and it reignited the part of me that just loves to create. 

It’s fast, thrilling, and yes, sometimes mentally draining, but in the way any great creative process can be.

Let me explain what I mean.

## Why vibe coding feels so addictive

Vibe coding has a rhythm that pulls you in. The AI writes code faster than you can imagine, and you watch your ideas come to life almost instantly while barely lifting a finger. 

It’s a kind of creative acceleration I’ve never experienced before. You get used to that pace, and it’s intoxicating.

### Just one more prompt

It starts innocently enough. You write one prompt to create a new feature. You make a few tweaks to test an idea. Then, suddenly, you’re chasing “just one more prompt.” 

The AI responds instantly, revealing things you might not have imagined yourself, sparking curiosity and adrenaline. It’s like gaming: one more level, one more round, one more challenge.

According to Lydia Chilton, Associate Professor of Computer Science at Columbia Engineering, [as cited by Columbia AI](https://ai.columbia.edu/news/ai-creativity-photography-art), innovation starts with the ‘flare’ stage, where you brainstorm ideas and solutions. She notes that AI amplifies this stage by letting you explore more ideas, run more experiments, and design faster than ever before.

That’s why, for me, each new prompt is like a mini-reward that gives me a dopamine rush. It’s a sort of high that I can’t get enough of.

### Speed feels like power

Traditional coding gives you natural pauses. Typing forces you to think, plan, and troubleshoot. 

With vibe coding, the AI does the code writing, and your only job is to keep up. Every result appears row by row, and your brain races to process it, evaluate it, and type in the next prompt.

It’s a creative flow in its purest form, an exhilarating conversation between you and the machine. 

I find myself doing it all the time: while drinking my morning coffee, during a break, or late at night when inspiration strikes.

Every prompt feeds the next. Every result creates a new possibility. The speed is empowering because it smooths things out between your thoughts and their realization.

## The other side of vibe coding

Like any powerful tool, vibe coding requires a bit of balance. The rush can blur time, and when the session ends, your mind feels both satisfied and exhausted.

You might wake up the next day mentally drained, replaying the ideas you explored the night before. 

For me, this is a sign of deep engagement, the same kind of creative fatigue that follows a productive all-night brainstorming session.

But not everyone agrees…

### Your brain can have a hard time keeping up

The biggest challenge of vibe coding is keeping your head in the game. You’re jumping between ideas, testing, prompting, debugging, and the output never stops.

[Researchers at MIT found that](https://www.media.mit.edu/projects/your-brain-on-chatgpt/overview/) extensive reliance on AI for creative tasks can reduce deep focus and comprehension. 

This makes sense because once you stop typing and start prompting, your brain is no longer engaged in the same way. 

Every time you skip reading and analyzing the AI-generated code, you give up a little bit of understanding. Over time, those skipped moments add up, and you can lose touch with how the system really works.

As Andrej Karpathy, the computer scientist who introduced the concept of vibe coding, [wrote in his now-famous post on X](https://x.com/karpathy/status/1886192184808149383?lang=en): “The code grows beyond my usual comprehension, I'd have to really read through it for a while.”

Still, vibe coding simply pushes you to think differently. As long as you stay curious and read what the AI produces, you can turn speed into skill.

### Everything can start to sound the same

The code looks clean, the structure makes sense, but it feels too familiar. It reads like a snippet from a coding tutorial on YouTube or a GitHub repo you’ve never seen but somehow recognize.

That’s the thing with AI-generated code: it can sometimes feel like everyone’s work and no one’s in particular, at the same time. It can have the shape of expertise, but lack creativity, until you add yours back in.

[According to Columbia AI](https://ai.columbia.edu/news/ai-creativity-photography-art), Lydia Chilton calls AI “reductive and fundamentally unoriginal” because it doesn’t know how to judge or refine what it generates.

This is where the human element comes in. Your quirks, your choices, your deviations from convention are what make the output yours.

When you bring your perspective into the loop, vibe coding stops being generic and starts being expressive and meaningful again.

## Where this could lead

Vibe coding shows what happens when creativity meets automation head-on. The line between thought and execution is gone. 

It’s a new kind of craftsmanship and it’s extraordinary!

Those long hours of debugging that used to build patience and precision can now be invested in design thinking, experimentation, or storytelling.

Even if the work changes its shape, your spirit can remain the same.

### Two directions

We can already see two paths forming:

* Some developers dive headfirst into the fast, freeform rhythm of vibe coding. 
* Others prefer [what Simon Willison calls ‘vibe engineering,](https://simonwillison.net/2025/Oct/7/vibe-engineering/)’ where AI tools improve your work but never replace your judgment. 

Both approaches work as long as you know when to let the AI lead and when to step in.

Vibe coding can make you feel like the ideas are racing ahead of you, but that’s part of its magic. The real skill is deciding which ideas are worth pursuing. 

You choose the problems that matter, the features that add value, and the solutions that feel right. Let AI handle the repetitive work while you focus on creativity, purpose, and direction.

## The bottom line

Vibe coding is a reminder that AI tools can speed up work and reignite curiosity. 

Every morning when I open my laptop, I feel the same spark that got me into coding in the first place. 

I prompt, I explore, I build, and it’s thrilling, but I still need to remind myself every once in a while to slow down and stay grounded.

If AI makes coding feel like a game, then the real skill now is learning to play it well.

Have you felt that pull too?

If you’ve found yourself chasing just one more prompt or losing track of time while coding with AI, I’d love to hear about it. How has vibe coding changed the way you create?

Elasticsearch vs Qdrant (vs Meilisearch): Which search solution actually fits your needs in 2025?

This is the third in our series on practical RAG with Meilisearch. In [post #1](https://www.meilisearch.com/blog/mastering-rag), we explained how hybrid retrieval (lexical + semantic) boosts both recall and precision so your results are actually the right ones. In [post #2](https://www.meilisearch.com/blog/rag-with-meilisearch), we walked through the full RAG pipeline: query refinement → retrieval → generation, and why keeping those pieces integrated keeps latency low and the system simple.

In this post, we focus on how teams actually ship. We’ll look at three patterns that show up over and over in real products: **R**etrieval, **A**nswers, and **G**rowth, and illustrate each with concrete use cases from teams using Meilisearch today.

## (R)etrieval: making the search bar fast, precise, and dependable

Shoppers don’t want an essay about sneakers; they want the right product card with a clean **'Add to cart' button**. In a commercial flow, generation is optional, but **retrieval quality** is everything. That’s the heart of the revenue pattern: make rank #1 correct, obvious, and fast, so the next click is a purchase, and not a string of revised queries.

![retrieve-find-results-fast.png](https://unable-actionable-car.media.strapiapp.com/retrieve_find_results_fast_84dd0e3314.png "Retrieve: Find results fast and accurately")

You can see this play out at [**Bookshop.org**](https://www.meilisearch.com/blog/bookshop-increases-search-based-purchases), where better retrieval directly translates into more purchases from search, increasing from 14% of searches leading to a purchase to 20%, a **43%** relative lift. That’s the sort of metric you feel in the revenue graph, and it came from relevance, not more copy. 

[**Minipouce**](https://www.meilisearch.com/blog/minipouce-top-grade-customer-experience) showcases the “great on day one” angle: solid defaults, typo tolerance, and intuitive facets produce results that feel right without weeks of tuning. 

And for teams outside classic retail, [**Qogita**](https://www.meilisearch.com/blog/qogita-simplifies-b2b-trade) (B2B marketplace) and [**HitPay**](https://www.meilisearch.com/blog/hitpay-streamlines-search) (fintech/commerce) exhibit the same retrieval-first pattern, dropping into very different surfaces: fast to set up, easy to operate, and friendly to lean teams.

What makes this work is a short, disciplined loop: hybrid ranking to catch both exact matches (“Air Max 270 black 42”) and intent phrasing (“black Nike runners size 9”), facets that narrow instantly, and a UI that respects the action. Keep an eye on zero-results queries, measure search→purchase conversion, and treat synonyms/typos as first-class relevance features. When intent is commercial, **R > G**: retrieval first, retrieval last.

## (A)nswers (retrieval + generation): one reliable answer beats ten links

Internal questions are scavenger hunts across policies, procedures, docs, tickets, and code. Your teammate doesn’t want ten blue links; they want a short, sourced answer they can act on. That’s where **retrieval + generation** shines: retrieval assembles the right building blocks; generation assembles them into a trustworthy and concise answer.

![answer-produce-accurate-answers.png](https://unable-actionable-car.media.strapiapp.com/answer_produce_accurate_answers_c4524820d2.png "Answer: Produce accurate answers synthesizing the searched results.")

In practice, [**Louis Vuitton**](https://eu.louisvuitton.com/eng-e1/homepage) is a clear example: store associates get consistent, fast answers to policy and product questions across locations. The value isn’t that an LLM can chat – it’s that retrieval surfaces current, canonical guidance, and generation condenses it into steps a person can follow. 

For developer productivity, [**Symfony**](https://www.meilisearch.com/blog/symfonys-solution-for-documentation-search) shows what low-latency, well-scoped search looks like at scale: sub-10 ms responses over **85,000+** docs across **30** versions help engineers land on the exact class, command, or procedure they need. At [**OCTO Technology**](https://www.meilisearch.com/blog/meilisearch-is-a-partner-of-choice-for-octo), the same approach operates as a dependable, production-ready solution in client environments where reliability and maintainability are crucial.

The craft is in the details: make retrieval source-aware (favor canonical and current, down-rank duplicates and stale pages), retrieve **snippets** instead of whole pages so the model stays on a short leash, and use a prompt that’s opinionated about behavior, yet can synthesize briefly, cite every claim, include steps or a code block when useful, and say “no evidence found” instead of guessing. A tiny feedback loop (“useful / missing / outdated”) helps you fix the source, not just the surface.

## (G)rowth (infrastructure): scale you don’t have to think about

Most RAG stories focus on search and answers. That’s great, until the demo grows up. The catalog doubles, traffic spikes on a Tuesday, someone adds three new locales, and suddenly your tidy prototype is juggling a keyword engine, a vector store, and a re-ranker stitched together with custom middleware. Queries get slow, dashboards get noisy, and your on-call starts carrying two laptops.

![grow-scale-effortlessly.png](https://unable-actionable-car.media.strapiapp.com/grow_scale_effortlessly_0f7c99ddde.png "Grow: Scale effortlessly as the data and customer base grow")

Some things are meant to be boring, and **scaling** should be one of them. Instead of an ever-changing stack where you tweak three services every time the user base grows, **Meilisearch offers one hybrid path** that stays fast as you add data, users, and languages. **One engine and one request handle both lexical precision and semantic recall.** No service hopping, fewer moving parts, and fewer surprises. As the client, you focus on content and UX, and we focus on the plumbing.

That’s the experience we aim for with Meilisearch. Index growth feels like adding shelves, not rebuilding the warehouse. Versioned indexes and safe schema changes turn “we need a new attribute” into a routine deployment. Language-aware analyzers, combined with embeddings, handle phrasing differences without a meeting. Monitoring covers what actually matters: latency *and* quality. That way you can spot recall/precision drift before users do. And vectors don’t have to eat your budget: compact embeddings, ANN indexes, and only storing what moves relevance keep costs sensible.

You can see this pattern in the wild. **CarbonGraph** moved from a standalone vector setup and found that adding embeddings inside a hybrid engine was straightforward, meaning no extra choreography was required. 

[**Hugging Face**](https://www.meilisearch.com/blog/hugging-face-democratizes-ai) is the stress test: discovery keeps working across **2.2M model cards**, **500k datasets**, and **60k demos** without turning every query into a science project. 

And for “hard-mode” content, [**TutKit**](https://www.meilisearch.com/blog/tutkit-multilingual-learning-at-scale) serves **15,000+** items in **26 languages**, while [**Bildhistoria**](https://www.meilisearch.com/blog/powering-bildhistoria-discovery) keeps **90,000+** richly annotated historical images findable and fast. Different shapes of data, the same quiet promise: it scales, and you barely notice.

## Ready, Aim, Go!

RAG isn’t one architecture; it’s a set of patterns you can plug in and ship. With Meilisearch, you get three practical pillars to build on: **Retrieve**, **Answer**, and **Grow**. **Retrieve** for quick discovery. **Answer** for concise, sourced guidance. **Grow** for speed and stability at scale. Start where you are, keep one path, and keep iterating.

Retrieve and gain: Three RAG use-case patterns you can ship today

Large language models (LLMs) are becoming better at handling larger context windows. But does that mean retrieval-augmented generation (RAG) is obsolete? Not quite. 

Here’s a quick look at what this guide covers:

* How RAG delivers grounded and user-friendly responses through retrieval and generation. 
* The hype surrounding long-context LLM models like Gemini 1.5 Pro or GPT-4.1, which can process thousands of tokens simultaneously.
* The major difference between RAG and long-context as well as the gap between them.
* When to use RAG and long-context LLMs, and what makes one better than the other in different situations. 
* A look at the pros and cons of each, and whether there is a need to use both together.
* How both RAG and long-context LLMs perform in real-world use cases, from AI agents to enterprise knowledge bases.

Let’s find out which approach gives you better, more grounded responses while incurring minimal costs.

## What is retrieval-augmented generation (RAG)?

[Retrieval-augmented generation](https://www.meilisearch.com/blog/what-is-rag) connects information retrieval with LLMs to generate accurate responses. How? By searching external knowledge bases or vector bases for relevant documents. 

RAG provides an LLM with retrieved chunks of external data, providing relevant context and helping it produce the response the user is looking for. 

As a result, RAG reduces the likelihood of AI hallucinations. It’s used in [AI agents](https://www.meilisearch.com/blog/agentic-rag) and real-time workflows that depend on external data.

Next, let’s take a look at how long-context LLMs handle larger context windows without retrieval.

## What is a long-context LLM?

A long-context LLM, as the name suggests, is a large language model specifically designed to handle a much larger context window size than the standard models. The difference is quite staggering, as it can sometimes process even millions of tokens without relying on retrieval.

Modern examples include GPT-4.1, Gemini 2.5 Pro, Claude 4 Opus, and Llama 4 Maverick. They can read entire reports, research papers, or knowledge bases at once, making them ideal for summarization, deep reasoning tasks, and extended document analysis.

Next, let’s compare how these long-context models differ from RAG.

## How does RAG differ from long-context LLMs?

The basic difference you need to understand between RAG and long-context LLMs is that they handle context differently. 

RAG retrieves relevant information from external sources before generation. Long-context LLMs, on the other hand, process all input within a single, long-context window. 

![RAG vs Long-Context LLMs.png](https://unable-actionable-car.media.strapiapp.com/RAG_vs_Long_Context_LL_Ms_cbc72da795.png)

While accuracy and scalability are goals for both approaches, the methods used to achieve them differ. 

If you’re exploring different architectures, our post on [RAG types](https://www.meilisearch.com/blog/rag-types) breaks down each variant with examples. 

Now, let’s see when using one of these is better than the other.

## When should you use RAG over long-context LLMs?

Retrieval-augmented generation is the perfect match when your app relies on external knowledge or dynamic datasets. If you need real-time retrieval and scalability, you can’t go wrong with RAG.

RAG handles changing knowledge bases and keeps latency predictable, minimizing the required number of tokens per query. 

It’s cost-effective and enables domain-specific optimization as well as granular access control for transparent audit trails. 

## When are long-context LLMs a better choice?

The best time to use long-context LLMs is when your data fits inside a single large context window and doesn’t change often. Summarization, reasoning, technical reports, understanding transcripts; they do it all. 

The newer models, such as GPT-4.1, Gemini 2.5 Pro, Claude 4 Opus, and Llama 4 Maverick, push context window sizes past a million tokens and easily handle complex cross-document reasoning. Additionally, these models can handle entire datasets directly, eliminating the need for retrieval pipelines.

As amazing as that sounds, it comes with a significant computational cost. The latency also goes up for larger inputs. 

In short, for static knowledge bases, more extended context exploration, or quick experimentation, long-context LLMs are often the more practical path.

## What are the main advantages of RAG?

RAG gives you all the control and flexibility you need to build faster and minimize costs when developing your system. 

Let’s see what makes RAG special:

1. **Efficient use of resources:** By retrieving only relevant documents, RAG keeps the number of tokens small, reduces costs, and speeds up each query.
2. **Speed:** Thanks to the use of vector bases and embedding models in the retrieval process, the speed of RAG systems is unmatched.
3. **Flexibility and adaptability:** RAG easily integrates with various knowledge bases, requiring no fine-tuning.
4. **Full transparency:** Every answer can point back to its retrieved chunks, so it can easily be traced while maintaining user trust.

## What are the main advantages of long-context LLMs?

Long-context LLMs are by far the best option when you need the system to handle large inputs while retaining the context. 

Let’s take a deeper look at their pros:

1. **Thorough understanding:** These models process entire datasets or documents in a single pass, ensuring minimal fragmentation and preserving the meaning.
2. **Exhaustive reasoning:** Long-context LLMs shine in reasoning tasks and can connect ideas spread across long sequences for stronger logical flow.
3. **Simplicity:** There’s no need for external RAG pipelines or vector databases. Just input your text and generate.

Now, it’s time to see the limitations of both RAG and long-context LLMs.

## What are the limitations of RAG?

RAG is the go-to option for accuracy and control, but that doesn’t mean it comes without challenges. Let’s look at some below:

1. **Retrieval is not 100% accurate:** You may sometimes receive poor output quality due to inadequate chunking and embedding models.
2. **Costly maintenance:** Keeping indexes fresh requires ongoing updates to datasets and managing data pipelines. None of this is free or easy.
3. **Experienced prompt engineering skills needed:** RAG depends on well-structured prompts to merge retrieved chunks without confusing the LLM.
4. **Latency changes too easily:** Each retrieval step adds milliseconds to the response time. When you estimate this at scale, it adds up to a significant amount of latency. 

These factors make RAG more complex to deploy and maintain than long-context LLMs, which is why small teams tend to avoid it.

## What are the limitations of long-context LLMs?

Let’s now explore the key drawbacks to long-context LLMs:

1. **Excessive resource use:** When you want to process millions of tokens, you need more computational resources.
2. **Scaling isn’t easy:** It’s not straightforward to scale long-context LLMs, as latency and response times increase with added context length.
3. **Lost context:** You can lose important details, especially in extremely long inputs or mixed datasets.
4. **Data security:** The larger the prompt, the greater the risk of prompt injection, which can lead to data leakage and compromise enterprise security.

Even advanced models face these issues when pushed to their context window size limits.

Next, we’ll examine how both methods perform using real-world benchmarks.

## How do RAG and long-context LLMs perform on benchmarks?

Numerous qualified studies offer nuanced insights into how each approach performs. 

Let’s look at some of the most recent papers that discuss this in detail.

[‘Retrieval Augmented Generation or Long-Context LLMs? A Comprehensive Study and Hybrid Approach’](https://arxiv.org/abs/2407.16833) (Li et al., 2024) found that long‐context LLMs consistently outperformed RAG when ample resources were available, but RAG was undoubtedly far more cost-efficient.

Another study, [‘LaRA: Benchmarking Retrieval-Augmented Generation and Long-Context LLMs – No Silver Bullet for LC or RAG Routing’](https://arxiv.org/abs/2502.09977) (Li et al., 2025), observed that there was no one-size-fits-all solution. The choice ultimately depends on the model size, task type, and other factors surrounding context length and retrieval quality.

Long-context models shine for long, static documents. On the other hand, RAG performs better when datasets are dynamic or diverse. 

## How do RAG and long-context LLMs impact costs?

It’s no secret that RAG offers lower overall costs for setup, while long-context LLMs incur a higher token and infrastructure cost at scale: 

* **Unique setup cost:** With RAG, the focus is on indexing, embedding, and retrieval. For LLMs, the focus is on a premium API or GPUs that support large context windows. 
* **Inference costs:** The inference cost for RAG is much lower since it only sends relevant chunks to the LLM. This way, it minimizes the token cost and usage. On the other hand, LLMs that are processing 200k+ tokens per request might even cost up to $20 per call. 
* **Scaling and maintenance costs:** RAG pipelines require ongoing index upkeep and retrieval tuning, but base LLM token consumption stays low. Long-context solutions scale poorly with more users or larger documents because each call incurs increased costs and latency.
* **Operational charges to consider:** Enterprises with strict cost or latency targets often choose RAG since it better suits their needs. For long-context LLMs, hidden costs like GPU usage, memory capacity, and slower responses become an uninvited guest that you don’t enjoy dealing with.

## What are real-world use cases for RAG?

RAG is ideal for domains that deal with rapidly changing contexts. These include:

1. **Enterprise knowledge systems:** Companies use RAG to consolidate all their internal data from wikis, emails, and CRMs into a unified knowledge base. AI assistants can then use this knowledge base to deliver relevant answers.
2. **Intelligent search engines:** RAG serves as the backbone for intelligent search engines. Thanks to vector databases and [hybrid retrieval](https://www.meilisearch.com/blog/hybrid-search), manual lookup time can be significantly reduced.
3. **Dynamic document management:** In fast-moving domains such as finance or healthcare, RAG enables real-time updates without requiring retraining of the AI model. This way, the output always reflects the latest updates.

## What are real-world use cases for long-context LLMs?

Long-context LLMs excel at handling tasks that require large inputs: 

1. **Summarization and analysis:** Models can process entire reports, transcripts, or books. They provide all the information you need from these sources, whether summaries, transcripts, or answers to questions that require reasoning.
2. **Legal and compliance review:** Long-context LLMs are a go-to choice for enterprises that need to review legal contracts in their entirety. They also help in flagging inaccurate info and comparing clauses without losing context.
3. **Academic and technical research:** Long-context systems can explore long datasets, scientific papers, or arXiv collections to identify relevant information and trends across different fields.

It’s now time to explain why LLMs’ growing capabilities are starting to challenge traditional RAG pipelines.

## Why are long-context LLMs challenging traditional RAG pipelines?

All these recent advances in context window size are reshaping how developers think about retrieval. 

Models that can handle over a million tokens reduce reliance on RAG pipelines and vector databases. For smaller or static datasets, long-context LLMs provide faster and simpler results without requiring any retrieval infrastructure. 

However, RAG remains undefeated when it comes to dynamic or real-time data retrieval, offering both data freshness and scalability.

Let’s see how to choose between these two approaches effectively.

## How to choose between RAG and long-context LLMs?

Choosing between RAG and long-context LLMs depends on your data volume, update frequency, and performance goals. Each approach can meet a distinct need:

1. **Project scope:** If the project is small or static, such as a policy chat or document summary, the long-context models are way easier to deploy. For larger projects that need real and ongoing reasoning, RAG is what you want.
2. **Data type and freshness:** If your system relies on constantly changing or real-time content (such as support tickets, logs, or news) RAG ensures the results remain current and up-to-date. 
3. **Scalability and cost:** RAG minimizes token usage, so it’s more cost-effective for enterprise-scale workflows. Long-context LLMs consume more tokens as the context length increases, resulting in increased latency and computational resources.
4. **Compliance and control:** When there can be no compromise with audit trails and explainability, such as in healthcare or finance, RAG’s indexed architecture provides audit-ready outputs. 

In short, RAG suits high-volume, dynamic ecosystems, while long-context LLMs excel in reasoning-intensive domains.

## How does retrieval work in RAG vs. long-context LLMs?

In RAG, retrieval happens before the model generates a reply. A retriever searches your knowledge base to find the most relevant documents, then passes the retrieved information to the large language model for response generation.

Tools like Meilisearch make this step even faster and production-ready. Meilisearch indexes content and performs hybrid retrieval (keyword + vector) with built-in filters, scoring, and reranking. This gives grounded and citable snippets that aren’t just accurate but also easy to track. It’s transparent and quick to update or scale through Meilisearch’s simple <code><em>/chat</em></code> API.

Long-context LLMs have no retrieval step at all. They rely entirely on what’s packed inside the prompt. 

While this works for short, static data, it becomes costly and less fresh as context windows grow. Additionally, there’s no automatic refresh or audit trails, so it is impossible to trace the origin of the response.

## Can RAG and long-context LLMs be combined?

Yes, and it’s often the best of both worlds. Hybrid setups use RAG to fetch relevant documents from a knowledge base, then feed them into a long-context LLM. Then comes the reasoning across the entire input combined.

This hybrid approach strikes the perfect balance between recall and reasoning. RAG ensures the prompts are lean and cost-effective, while the long-context LLMs handle the analysis and reasoning the user requires.

Meilisearch handles the retrieval layer in such systems: indexing, filtering, and returning grounded, high-quality snippets before the model processes them.

If you’re into experimenting with model correction or hybrid routing, explore [our guide on corrective RAG](https://www.meilisearch.com/blog/corrective-rag) for practical strategies.

## Bringing it together: choosing between RAG and long-context LLMs

Both RAG and long-context LLMs push the limits of how large language models use data, but their goals differ significantly from one another. 

RAG is all about accuracy and efficiency, but long-context LLMs excel in reasoning and retaining context. 

The best foundation you can build for any system is to combine both of them.
