> When returning facet.field=<name of field> you will get a list of matches for
> distinct values. This is normal behavior. This patch tells you how many
> distinct values you have (# of rows). Use with limit=-1 and mincount=1.
> The feature is called "namedistinct". Here is an example:
> http://localhost:8983/solr/select?q=*:*&facet=true&facet.field=manu&facet.mincount=1&facet.limit=-1&f.manu.facet.namedistinct=0&facet.field=price&f.price.facet.namedistinct=1
> Here is an example on field "hgid" (without namedistinct):
> {code}
> - <lst name="facet_fields">
> - <lst name="hgid">
> <int name="HGPY0000045FD36D4000A">1</int>
> <int name="HGPY00000FBC6690453A9">1</int>
> <int name="HGPY00001E44ED6C4FB3B">1</int>
> <int name="HGPY00001FA631034A1B8">1</int>
> <int name="HGPY00003317ABAC43B48">1</int>
> <int name="HGPY00003A17B2294CB5A">5</int>
> <int name="HGPY00003ADD2B3D48C39">1</int>
> </lst>
> </lst>
> {code}
> With namedistinct (HGPY0000045FD36D4000A, HGPY00000FBC6690453A9,
> HGPY00001E44ED6C4FB3B, HGPY00001FA631034A1B8, HGPY00003317ABAC43B48,
> HGPY00003A17B2294CB5A, HGPY00003ADD2B3D48C39). This returns number of rows
> (7), not the number of values (11).
> {code}
> - <lst name="facet_fields">
> - <lst name="hgid">
> <int name="_count_">7</int>
> </lst>
> </lst>
> {code}
> This works actually really good to get total number of fields for a
> group.field=hgid. Enjoy!
