Re: Getting only size of getFacetCounts , to simulate count(group by( a field) ) using facets

[cricdigs <cr...@gmail.com>]

Hi,

Not sure what the resolution on this has been. But, I also have this need
and I am using 1.2 release of solr. If there is a workaround so I can get
this functionality, please advise. It will be very helpful.

Thanks.
