I actually submitted a patch a while ago in Solr-2052 that allows you to specify a bit filter and a filter query (you could specify either, but not both.) Otis pointed out that the patch can't be applied against the current source, so I need to go back and make it work with the current source (new job = no time). I'll see if I can find the time this weekend to do this. Steve -- Stephen Green http://thesearchguy.wordpress.com
