# Amazon OpenSearch

Amazon OpenSearch Service is a managed retrieval engine built on OpenSearch for agentic AI, search, and analytics. It combines vector, lexical, and hybrid retrieval in one system, using HNSW and IVF indexing with vector quantization. Customers can run fully managed clusters or the Serverless option, and AWS calls it the recommended vector database for Amazon Bedrock.
