Hybrid search

Elastic Stack Serverless

Hybrid search combines traditional full-text search with AI-powered search for more powerful search experiences that serve a wider range of user needs.

The recommended way to use hybrid search in the Elastic Stack is following the semantic_text workflow. Check out the hands-on tutorial for a step-by-step guide.

We recommend implementing hybrid search with the reciprocal rank fusion (RRF) algorithm. This approach merges rankings from both semantic and lexical queries, giving more weight to results that rank high in either search. This ensures that the final results are balanced and relevant.
