Required. Name of the source to groupBy. If no location is specified,
 finding is assumed to be in global.
  The following list shows some examples:
 `organizations/[organization_id]/sources/[source_id]`
 `organizations/[organization_id]/sources/[source_id]/locations/[location_id]`
 `folders/[folder_id]/sources/[source_id]`
 `folders/[folder_id]/sources/[source_id]/locations/[location_id]`
 `projects/[project_id]/sources/[source_id]`
 `projects/[project_id]/sources/[source_id]/locations/[location_id]`
 To groupBy across all sources provide a source_id of `-`. The following
 list shows some examples:
 `organizations/{organization_id}/sources/-`
 `organizations/{organization_id}/sources/-/locations/[location_id]`
 `folders/{folder_id}/sources/-`
 `folders/{folder_id}/sources/-/locations/[location_id]`
 `projects/{project_id}/sources/-`
 `projects/{project_id}/sources/-/locations/[location_id]`
