> This is the first step for SOLR-8228 Facet Telemetry. It's going to implement
> the telemetry for a nested facet query and put the information obtained in
> debug field in response.
> Here is an example of telemetry returned from query.
> Query
> {code}
> curl http://localhost:8228/solr/films/select -d
> 'q=*:*&wt=json&indent=true&debugQuery=true&json.facet={
> top_genre: {
> type:terms,
> field:genre,
> numBucket:true,
> limit:2,
> facet: {
> top_director: {
> type:terms,
> field:directed_by,
> numBuckets:true,
> limit:2
> },
> first_release: {
> type:terms,
> field:initial_release_date,
> sort:{index:asc},
> numBuckets:true,
> limit:2
> }
> }
> }
> }'
