Azure AI Search

Managed AI service for enterprise-grade information retrieval: delivers vector, hybrid, and semantic search over your proprietary data.

Azure AI Search (formerly Azure Cognitive Search) is your fully managed cloud solution for intelligent data retrieval. It handles the heavy lifting: ingest proprietary content from sources like Azure Blob Storage, enrich it with Azure AI services (OCR, entity recognition), and build a high-performance index. The core strength is its advanced retrieval stack: deploy vector search for meaning-based matching, keyword search for precision, or hybrid retrieval combining both for superior relevance. This platform is essential for grounding large language models (LLMs) in Retrieval-Augmented Generation (RAG) architectures, ensuring your AI agents provide accurate, context-aware answers from your private knowledge base.
