Elasticsearch Relevance Engine (ESRE) documentation

Beyond full-text search

The Elasticsearch Relevance Engine (ESRE) is a collection of relevance tools for developing advanced search applications using machine learning (ML) and artificial intelligence (AI).

Expand your usage of Elasticsearch by combining keyword matching with semantic search and integrations with generative AI. Provide search results based on contextual meaning and user intent, or display generated answers and other relevant content in response to user input.

Learn more about the Elastic features that compose ESRE, view example applications and notebooks, or get help with your specific application.
