Specifies a structured query that filters the results of a search without affecting how the results are scored
and sorted. You use <code>filterQuery</code> in conjunction with the <code>query</code> parameter to filter the
documents that match the constraints specified in the <code>query</code> parameter. Specifying a filter controls
only which matching documents are included in the results, it has no effect on how they are scored and sorted.
The <code>filterQuery</code> parameter supports the full structured query syntax.
