Yes, Solr would actually collect 0-20, but the entire set of matching documents must still be scored to find the maximum score. So if the threshold will be a function of maxScore, it still requires two passes, no? > There is more.

This sounds like field collapsing. There's is a patch that's still in the works: http://wiki.apache.org/solr/FieldCollapsing -Yonik http://www.lucidimagination.com
