# Azure AI Search

Azure AI Search is a cloud search service from Microsoft that provides full-text, vector, and hybrid search over indexed content. It can generate embeddings during indexing or at query time through its indexer pipeline, and it can merge hybrid results with Reciprocal Rank Fusion. It was renamed from Azure Cognitive Search in November 2023 and runs as a dedicated search engine with persistent storage of searchable content.
