Azure Cognitive Search

Deploy a fully managed, AI-powered search service: instantly integrate full-text, vector, and semantic ranking over your enterprise data.

Azure Cognitive Search (now Azure AI Search) is the PaaS solution for enterprise-grade information retrieval. It handles the indexing of diverse content from sources like Azure Blob Storage and Cosmos DB. The platform’s core strength is its AI enrichment pipeline, which uses skillsets for tasks like OCR, key phrase extraction, and integrated vectorization, transforming unstructured data into searchable content. Developers leverage its REST APIs and SDKs (.NET, Python) to deliver high-relevance search experiences, featuring hybrid search and sophisticated semantic ranking for superior accuracy.
