Hi Joshua,
The functionality you are asking about is requested by
https://issues.apache.org/jira/browse/SOLR-5743.
I've prepared a patch with initial implementation and going to speak about
it on Lucene/Solr Revolution 2014 Conference, held in Washington, DC on
November 11-14, http://lucenerevolution.org/.
Please see 'Faceting with Lucene BlockJoinQuery' talk announcement in
Internals Sessions.
You are very welcome to join the conference and participate in discussion.
Your vote for https://issues.apache.org/jira/browse/SOLR-5743 would also be
match appreciated.
Thank you,
