Benefits of Azure Search

  • Sophisticated search capabilities: including real-time indexing, geosearch, pattern search, and search on machine data.
  • Managed Service: results in lower cost and less work by eliminating the need to deal with servers, software updates, backups, etc.  If you are already using Azure, then you can quickly provision new indexes in your existing subscription and connect to your enterprise systems using Indexing Connectors over your current networking.
  • High Degree of Control: including direct control of relevance ranking, query processing, and indexing.
  • Scale-up: Azure search provides extreme scale and a pay-as-you-grow model. If you are hitting the limits of SharePoint Online search (such as files over 64MB or large amounts of data outside of Office 365), then you can use Azure search to supplement your existing search and present users with a single unified result set through SmartHub.
