This sounds like grouping: http://wiki.apache.org/solr/FieldCollapsing Unfortunately it only works on single values fields, and you can't sort based on numbers of matches either. The closest you can get today is to issue 2 requests... the first a faceting request to get the top constraints, and then a second that uses group.query for each constraint you are interested in. -Yonik http://www.lucidimagination.com
