        Use the filter parameter to narrow results and the fields parameter to

        select which fields are returned.


        When the filter targets the cache key field with an "in" operator,

        the server performs direct cache lookups instead of scanning all records.

        Additional filters in the same request are applied to the narrowed set.'
