Azure Cognitive Search
Enterprise scale search for app development.
Uncover latent insights from all your content
Azure Cognitive Search is the only cloud search service with built-in AI capabilities that enrich all types of information to help you identify and explore relevant content at scale. Use cognitive skills for vision, language, and speech, or use custom machine learning models to uncover insights from all types of content. Azure Cognitive Search also offers semantic search capability, which uses advanced machine learning techniques to understand user intent and contextually rank the most relevant search results. Spend more time innovating and less time maintaining a complex cloud search solution.
Fully managed search as a service to reduce complexity and scale easily
Auto-complete, geospatial search, filtering, and faceting capabilities for a rich user experience
Built-in AI capabilities including OCR, key phrase extraction, and named entity recognition to unlock insights
Semantic search capability powered by deep learning models that understand user intent to surface and rank the most relevant search results
Start, maintain, and scale with minimal investment
Deploy a search index quickly and avoid operational maintenance. This fully managed cloud search service reduces the complexity of data ingestion and index creation by integrating with popular Azure storage solutions and offering index functionality exposed through a simple REST API or .NET SDK. 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.
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.
Surface the most relevant results for your users based on search intent and not just keywords
Leverage tried-and-tested deep learning models from Microsoft Research and Bing to provide contextual and most relevant results in your apps. Using semantic search capability, you can understand the intent of what your customers are trying to search, offer significantly improved search results and drive deeper customer engagement. Semantic search also enables summary results so your users can get quick snippet without the need to go through results links and full documents.
