Uncover latent insights from all your content
Azure Search is the only cloud search service with built-in artificial intelligence (AI) capabilities that enrich all types of information to easily identify and explore relevant content at scale. It uses the same integrated Microsoft natural language stack that Bing and Office have used for more than a decade, and prebuilt AI APIs across vision, language, and speech. 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
Flexible integration of custom models, classifiers, and rankers to fit your domain-specific needs
Import data from popular Azure Stores, or ingest from other sources via Push API
Configure your search index with pre-populated fields from your content
Index or query test your data
Manage in the Azure portal or with .NET SDK and REST APIs
Scale your search service as storage and performance needs fluctuate
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 pre-trained AI models
Take advantage of pre-trained speech, vision, and language models that transform raw, unstructured information into searchable content. Using the cognitive search feature, create enrichment pipelines that use built-in AI APIs to bring structure to your data before it gets indexed, either programmatically or while staying in the Azure Search portal. Applying AI capabilities such as OCR, key phrase extraction, location, people, and organization detection is as simple as checking a box in the Azure Search portal.
Customize to meet business goals and industry requirements
Extend the Azure Search platform to match your specific business goals and industry. 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.
