Facets are missing post updating Apache Solr Search to 7.x-1.4 version I just updated Apache Solr Search module to 7.x-1.4 version, and since then the facets are missing in the assigned region.

Facets of all taxonomy terms are missing, the rest of the default facets like content type, etc are appearing on the settings page.

Plus the Taxonomy term fields are missing under Bias settings as well.

I have tried to disable > Uninstall > re-install all the Apache solr search and Acquia search modules but Facts are not appearing back on the Apache Solr Settings page.

I have this issue on the production server.

Just wanted to log the answer that is suggested on Drupal.org: https://drupal.org/node/2123683, since this question is the first thing that popped up when I ran into this issue.  :0)

Here is the issue: the taxonomy facets are the ones affected by the upgrade, because even though your taxonomy terms are probably hidden in the 'Search index' view mode on your content type's configuration page, apachesolr used to ignore those settings (a bug).

The new update fixes that, which means you need to go back to your content type's manage display page -> search index tab -> make sure the taxonomy terms in question are not hidden.

Hope this helps!
