Retrieving query suggestions using the Search REST service

  • Článek

Learn how you can use the Search REST service from your client and mobile applications to retrieve query suggestions from Search in SharePoint. Query suggestions, also known as search suggestions, are phrases that users have already searched for and that are displayed or "suggested" to them as they type their queries. You can use Search in SharePoint to turn on pre-query and post-query suggestions. These suggestions appear in a list below the Search box as a user types a query. For more information about query suggestions and how to enable them, see Manage query suggestions in SharePoint.

Suggest endpoint in the Search REST service

The Search REST service includes a Suggest endpoint you can use in any technology that supports REST web requests to retrieve query suggestions that the search system generates for a query from client or mobile applications.

The URI for GET requests to the Search REST service's Suggest endpoint is:

/_api/search/suggest

The query suggestion parameters are specified in the URL. You can construct the request URL in two ways:

http://server/_api/search/suggest?parameter=value&parameter=value

http://server/_api/search/suggest(parameter=value&parameter=value)

Note

The Search REST service doesn't support anonymous requests to the Suggest endpoint.
