Use the Microsoft Search API to search custom types imported using Microsoft Graph connectors

  • 아티클

Use the Microsoft Search API in Microsoft Graph to search across external content ingested and indexed by Microsoft Graph connectors. The content is imported either via built-in connectors provided by Microsoft, or via custom connectors implemented by using the Microsoft Graph connectors ingestion API.

Caution

The search API schema has changed in the beta version. Some properties in a search request and response have been renamed or removed. For details, see Schema change deprecation warning. The examples in this topic show the up-to-date schema.

After the content has been imported and indexed, you can use the search API to query the content.

To search for custom types, specify the following properties in the request body of the query method:

  • The contentSources property to include the connection ID that is assigned during the connector setup. You can pass multiple connection IDs to search across multiple connections. Results are returned in a single list, ranked across the multiple connections.

  • The entityTypes property as externalItem.

  • The fields property to include the fields in the external item to retrieve. Note that if you do not include any fields in the request, the response will contain all the fields marked as retrievable in the data schema specified for the specified connections in the contentSources property.

In addition, you can aggregate search results based on properties in an externalItem that are numeric or string type, and that are set to be refinable in the schema. For more information, see Refine search results using aggregations.

Example 1: Retrieve items using Azure SQL built-in connector

In this example, the content of the AdventureWorks database has been ingested using the Azure SQL built-in connector.
