there is actually an interesting trick here using facet.query (which would only entail a single filter cache entry):
http://127.0.0.1:8888/solr/collection1/select?q={!tag=main}country:Spain&facet=on&facet.query={!ex=main key=total}*:* [my test data has a country field] Using facet tagging/exclusion you can get the total amount. Note that you'll have to tag fq params and ex(clude) those as well on the facet.query ex sub-parameter, like this sort of thing: http://127.0.0.1:8888/solr/collection1/select?q={!tag=main}country:US&facet=on&facet.query={!ex=main,fq1 key=total}*:*&fq={!tag=fq1}last_name:Smith With these you'll get a facet_querys/total section in the response with the total number of documents regardless of q/fq constraints.
