> Non-JSON facet is widely used and telemetry is helpful is diagnosing expensive queries. As first step, the JIRA is to design telemetry for field facet.
> Example: (using films)
> {code}
> $curl 'http://localhost:8228/solr/films/select?debugQuery=true&facet.field=genre&facet.field=directed_by&facet=true&indent=on&q=*:*&wt=json'
> ...

>           "processor":"SimpleFacets",
>           "elapse":1,
>           "action":"field facet",
