# 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]({{site.url}}{{site.baseurl}}/search-plugins/search-relevance/compare-search-results/) from two queries side by side in OpenSearch Dashboards.
- [Reranking search results]({{site.url}}{{site.baseurl}}/search-plugins/search-relevance/reranking-search-results/) using a cross-encoder reranker.
- Rewriting queries using [Querqy]({{site.url}}{{site.baseurl}}/search-plugins/querqy/).
