Does anybody know, how I can get all my taxonomy_term_references for my video content type to be listed as Facet options on the Configuration > Apache Solr search > Facets tab (admin/config/search/apachesolr/settings/solr/facets)? I am trying to fix the search on an existing Drupal site that wasn't built by me and I can only see one taxonomy_term_reference for one vocabulary, but not all of them. The site uses Display Suite as well.
Here is a screenshot of my Facet tab: Screenshot of facets
I think I sold this myself. But wow, why isn't there any documentation for this.
A couple of configuration need to be set:

Enable search results (Step 1)
Add taxonomy to search results (Step 2)
Select facet (Step 4)
