Method: query.search

The Cloud Search Query API provides the search method, which returns the most relevant results from a user query. The results can come from G Suite 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 G Suite domain-wide delegation of authority.

HTTP request

POST https://cloudsearch.googleapis.com/v1/query/search

The URL uses gRPC Transcoding syntax.

Fields
queryInterpretation

resultCounts

object (ResultCounts)

Expanded result count information.

Union field result_count. The total result count across all requested data sources. Omitted if predefined sources are included in the set of data sources queried. Result counts might be returned as an estimate, instead of exact, under the following circumstances:

  • When the query has more than 2 terms in a phrase, such as "result count exact" in quotes.

  • When the number of unique search result ACLs to evaluate are too large to compute within a reasonable latency.

In the rare case when the system is unable to search through all documents, rerun the query. result_count can be only one of the following:
resultCountEstimate

string (int64 format)

The estimated result count for this query.
resultCountExact

string (int64 format)

The exact result count for this query.
