Amazon OpenSearch Service now supports OpenSearch version 2.11

You can now run OpenSearch version 2.11 in Amazon OpenSearch Service. With OpenSearch 2.11, we have made several improvements to search, observability, security analytics, and OpenSearch Dashboards. This version includes features that were launched as part of open source OpenSearch versions 2.10 and 2.11. This launch includes the introduction of hybrid search queries, which uses normalization processors to improve search relevance, by combining relevance scores of lexical queries with natural language-based k-NN vector search queries. It also includes multimodal search, which allows users to search image and text pairs like product catalog items, and the introduction of neural sparse retrieval in addition to existing dense retrieval for semantic search applications. Search practitioners can test out these new search methods with the new search comparison tool which lets you compare the results of two different search queries side by side in OpenSearch Dashboards.
