RAG with context you can trust

AI applications must deliver accurate results at scale to build user trust. Ground large language models (LLMs) with the accuracy of Elasticsearch hybrid retrieval, and scale retrieval augmented generation (RAG) that's low latency and high efficiency.

RAG built for unmatched accuracy and efficient vector scaling

Deliver the right context with the vector performance, cost efficiency, and security that production demands.

The architecture behind context‑aware RAG

Connect your private data with secure hybrid search and managed inference, ground LLM responses with access controls, and deliver fast, observable, production-ready answers at scale.

Diagram showing Elasticsearch powering RAG by ingesting private data through connectors, applying secure hybrid search across lexical and vector retrieval, and grounding LLM responses via Elastic Inference Service. Built-in security, observability, and flexible deployment options support fast, accurate answers at scale.

Frequently asked questions

What is RAG in AI?

Retrieval augmented generation (commonly referred to as RAG) is a natural language processing pattern that enables enterprises to search proprietary data sources and provide context that grounds large language models. This allows for more accurate, real-time responses in generative AI (GenAI) applications.

What are the benefits of RAG?

When implemented optimally, RAG provides secure access to relevant, domain-specific proprietary data in real time. It can reduce the incidence of hallucination in generative AI applications and increase the precision of responses.

What are the benefits of using Elastic for RAG workflows?

Elastic makes RAG production-ready by solving the hardest parts out of the box: ingesting and grounding high-quality data, delivering accurate and efficient retrieval at scale, enforcing role- and document-level security, and preserving source attribution for trustworthy responses. With native vector, lexical, and hybrid retrieval; first-party models like ELSER and flexible third-party model integrations across the GenAI ecosystem; and proven performance at enterprise scale, Elastic helps teams build RAG systems that are faster to launch, easier to tune, and reliable in production.

How does Elasticsearch enable context engineering?

Elasticsearch is built for relevance at scale, which is the foundation of context engineering. It brings together vector, keyword, and structured search with analytics, inference, and observability in a single platform. This makes it easy for developers to store, retrieve, and rank structured and unstructured business data with precision, so agents always get the right context.

With Agent Builder, Elasticsearch takes this further by bringing chat, retrieval, tool creation, and orchestration directly into the platform. Developers can build, test, and scale context-driven agents in minutes using their own data, models, and tools, all supported by Elasticsearch relevance, security, and performance.
