Overview for extending the Microsoft Search experience for apps on Microsoft Graph (preview)

Microsoft Search is an enterprise search engine that delivers productivity gains and relevant search results for your organization. It harnesses the collective knowledge and productivity of an organization, and surfaces relevant content to keep end users up to date. Microsoft Search is available in various experiences including Office, SharePoint, Delve, Windows, and Bing.

Important

Microsoft Graph connectors and Microsoft Search APIs (query and index) are currently in preview status. To use connectors with Microsoft Search or to build connectors, you must sign up for the connectors preview program. To join the preview program, submit the Microsoft Graph connectors preview sign-up form.

Why use the Microsoft Search API?

One unified search endpoint for Microsoft cloud data

The Microsoft Search API provides one unified search endpoint to let developers query data in the Microsoft cloud - messages and events in Outlook mailboxes, and files on OneDrive and SharePoint - data that Microsoft Search already indexes.

Include custom external data in search experience

Customers who want to include data outside of the Microsoft cloud in their search experience can use connectors to connect to a specific data source such as an organization's human resources database or product catalog, and use the Microsoft Search API to seamlessly query the external data source. The Microsoft Graph connectors gallery lists a number of ready-to-use connectors. Alternatively, customers can build connectors, index external custom items and files, and query specific external data sources as well.

Consistent, up-to-date search experience

Using the Microsoft Search API, customers benefit from getting more personalized relevant results powered by Microsoft Graph. This also makes search in your apps return results consistent with search in Office applications.
