Search relevance

Search relevance evaluates the accuracy of the search results returned by a query. The higher the relevance, the better the search engine.

OpenSearch provides the following search relevance features:

• Comparing search results from two queries side by side in OpenSearch Dashboards.

• Reranking search results using a cross-encoder reranker.

• Rewriting queries using Querqy.
