* of an index. Field usage statistics are automatically captured when queries
* are running on a cluster. A shard-level search request that accesses a given
* field, even if multiple times during that request, is counted as a single
* use.
*
* The response body reports the per-shard usage count of the data structures
* that back the fields in the index. A given request will increment each count
* by a maximum value of 1, even if the request accesses the same field multiple
* times.
