The Cloud Search query API provides the search method, which returns the most relevant results from a user query. The results can come from Google Workspace apps, such as Gmail or Google Drive, or they can come from data that you have indexed from a third party.
Note:This API requires a standard end user account to execute. A service account can't perform query API requests directly; to use a service account to perform queries, set up Google Workspace domain-wide delegation of authority .
