Hi Gene, Solr supports this (faceted search) out-of-the-box.
Take a look at: http://wiki.apache.org/solr/SimpleFacetParameters http://wiki.apache.org/solr/SolrFacetingOverview It will give you words with their frequencies for the fields you select. However, it will give you all the facets (tags) and your front-end must do the filtering with the master list.
