I created issue https://issues.apache.org/jira/browse/SOLR-3062 for this problem. I was able to track it down to something in this commit - http://svn.apache.org/viewvc?view=revision&revision=1188624 (LUCENE-1536: Filters can now be applied down-low, if their DocIdSet implements a new bits() method, returning all documents in a random access way ) - before that commit the join / fq functionality works as expected / documented on the wiki page. After that commit it's broken.
Any assistance is greatly appreciated! Thanks, Mike On Thu, Jan 26, 2012 at 11:04 AM, Mike Hugo <m...@piragua.com> wrote: > Hello, > > I'm trying out the Solr JOIN query functionality on trunk.
