Description

Queries a knowledge base and generates responses based on the retrieved results, with output in streaming format. The CLI doesn't support streaming operations in Amazon Bedrock, including InvokeModelWithResponseStream. This operation requires permission for the bedrock:RetrieveAndGenerate action.

-VectorSearchConfiguration_OverrideSearchType <SearchType>
By default, Amazon Bedrock decides a search strategy for you. If you're using an Amazon OpenSearch Serverless vector store that contains a filterable text field, you can specify whether to query the knowledge base with a HYBRID search using both vector embeddings and raw text, or SEMANTIC search using only vector embeddings. For other vector store configurations, only SEMANTIC search is available. For more information, see Test a knowledge base.
