Oh, okay. Got it now. Unfortunately I don't believe Solr supplies a total count of matching facet values. One way to do this, although performance may suffer, is to set your limit to -1 and just get back everything, that will give you the count. You may want to set mincount to 1 so you aren't counting facet values that aren't in your query, but that really depends on your need.
...&facet.limit=-1&facet.mincount=1 adding that to any facet query will return all matching facet values. Depending on how many unique values you have, this could be a lot. But it will give you what you are looking for. Unless your data changes frequently, maybe you can call it once and cache the results for some period of time. -- View this message in context: http://lucene.472066.n3.nabble.com/Finding-distinct-unique-IDs-in-documents-returned-by-fq-Urgent-Help-Req-tp971883p978548.html Sent from the Solr - User mailing list archive at Nabble.com.
