Hi, There is no support with calculating facets, because the counts can't be optimized with wand or blockmax.
The general recommendation is to execute facets/aggregations in separate Elasticsearch or Solr requests (e.g. using AJAX on your website). The display of search results would be instant and facets coming later. Doing that in the same request or separately does not really matter for performance. So I'd always recommend to do it separately if you can do that in your user interface.
