Simplify development and delivery of search solutions
Reduce the complexity of data ingestion and search index creation through integration with Azure storage solutions and simple RESTful APIs and SDKs. Deploy a fully configured search service with intuitive user experiences such as scoring, faceting, suggestions, synonyms, and geo-search—all while avoiding the operational overhead needed to debug index corruption, monitor service availability, or manually scale during traffic fluctuations.
Customize search capabilities with AI integrations
Tailor the search experience to meet the unique requirements of your organization. Azure Cognitive Search offers customizable capabilities such as key phrase extraction, language detection, optical character recognition (OCR), image analysis, translation, and role-based access control (RBAC). Take advantage of integration with Azure AI services including Speech, Vision, Language, Decision, and Azure OpenAI Service to further transform raw, unstructured information into searchable content.
Surface the most relevant results for your users
Use advanced deep-learning models from Microsoft Research and Bing to provide contextual and relevant results in your apps. Employ the Azure Cognitive Search semantic search capability to understand the intent of customers’ search terms, offer significantly improved search results, and drive deeper customer engagement. Semantic search also enables summary results so your users can get quick snippet results without the need to scroll through results links and full documents.
Scale to handle large datasets and high-traffic loads
Azure Cognitive Search is designed to handle large amounts of data and support high-traffic loads, ensuring that your search solution can scale as your organization grows. Whether you're a small business or a large enterprise, easily index and search through massive amounts of data to deliver a great search experience for your users without worrying about managing infrastructure.
Create next-generation apps with Azure OpenAI Service
Combine Azure Cognitive Search with Azure OpenAI Service to apply the most advanced AI language models to your search solutions using your own data as the basis for responses. Use conversational language for knowledge base retrieval on enterprise data with ChatGPT, now available in Azure OpenAI Service (in preview).
