 # Features of Azure Cognitive Search
 
-Azure Cognitive Search provides a full-text search engine, persistent storage of search indexes, integrated AI used during indexing to extract more text and structure, and APIs and tools. 
+Azure Cognitive Search provides information retrieval and uses optional AI integration to extract more text and structure content. 
 
 The following table summarizes features by category. For more information about how Cognitive Search compares with other search technologies, see [Compare search options](search-what-is-azure-search.md#compare-search-options).
 
+There's feature parity in all Azure public, private, and sovereign clouds, but some features aren't supported in specific regions. For more information, see [product availability by region](https://azure.microsoft.com/explore/global-infrastructure/products-by-region/?products=search&regions=all&rar=true).

Internally, inbound text is processed into tokens and store in inverted indexes, and inbound vectors are stored in vector indexes.

 Azure Cognitive Search is well suited for the following application scenarios:
 
-+ Consolidate heterogeneous content into a private, user-defined search index. 
++ Search over your content, isolated from the internet.

 + Offload indexing and query workloads onto a dedicated search service.
 
 + Easily implement search-related features: relevance tuning, faceted navigation, filters (including geo-spatial search), synonym mapping, and autocomplete.

 + Add linguistic or custom text analysis. If you have non-English content, Azure Cognitive Search supports both Lucene analyzers and Microsoft's natural language processors. You can also configure analyzers to achieve specialized processing of raw content, such as filtering out diacritics, or recognizing and preserving patterns in strings.
