Azure 认知搜索

用于移动和 Web 应用开发的 AI 支持的云搜索服务


Azure Cognitive Search is the only cloud search service with built-in AI capabilities that enrich all types of information to easily identify and explore relevant content at scale. Formerly known as Azure Search, it uses the same integrated Microsoft natural language stack that Bing and Office have used for more than a decade, and AI services across vision, language, and speech. Spend more time innovating and less time maintaining a complex cloud search solution.

快速部署搜索索引,避免进行运营维护。此完全托管的云搜索服务与热门的 Azure 存储解决方案相集成并提供通过简单的 REST API 或 .NET SDK 公开的索引功能,从而降低数据引入和索引创建的复杂性。部署带有直观用户体验的已完全配置的搜索服务(例如评分、facet、建议、同义词和地理搜索),同时能够避免调试索引损坏、监控服务可用性或在流量变动期间手动进行缩放所需的运营开销。


Create searchable content using integrated AI

Take advantage of Azure AI speech, vision, and language services to transform raw, unstructured information into searchable content. Easily orchestrate AI services that bring structure to your data before it’s indexed by defining your own Cognitive Search skillset. Applying AI capabilities such as OCR, translation, key phrase extraction, location, people, and organization detection is as simple as checking a box in the Cognitive Search portal.


Extend the Cognitive Search platform to match your specific business goals and industry requirements. Better understand your data using custom models and classifiers, such as legal clause classifiers or manufacturing material identifiers, available in any language or framework. After you’ve deployed your cloud search service, quickly adjust your search results using rich, custom-tuned ranking models to tie your results to your business goals.



  • Protect your content from malicious acts with encryption built in throughout the entire indexing pipeline.
  • Maintain security with support for virtual networks.
  • Meet a broad set of international and industry-specific compliance standards.
  • Control per-user access to content through security filters.
