No, but this is a fast operation anyway (In Solr 1.4 at least). Another thing to watch out for is to not try this with filters that you don't know the size of (or else you may force a popcount on a BitDocSet that would not otherwise have been needed). It could also potentially complicate warming queries - need to be careful that the combination of filters you are warming with matches something, or it would cause the fieldCache entries to not be populated. -Yonik http://www.lucidimagination.com
