We're using Solr 4.0 Beta, testing the hierarchical faceting support to see if it's a good fit to facet on taxonomies. One issue we've encountered is that we can't apply filter exclusions to the hierarchical facets so as to preserve facet count with multi-select. I haven't been able to locate or otherwise determine if there's documentation that would outline how this is done. We've tried a few things with local params but it appears those aren't parsed with the facet.pivot argument. I found this ticket related to that:
https://issues.apache.org/jira/browse/SOLR-2255 Could anyone offer some insight or guidance on this?
