I have two search taxonomies – “style” and “mood” that are set up in a search form as checkboxes. Items can have multiple moods, but only one style. The search isn’t working properly, because it’s not screening out empty terms. Here’s a link:

Steps to replicate:

1. Click on the “style” filter up at the top to expand it
2. Check “modern” and “rustic”. That filters out only the items that have modern or rustic styles, and it works properly.
3. Now expand the “mood” filter and click on “whimsical”. Nothing happens because there are no items that are either modern or rustic AND whimsical. So the whimsical choice shouldn’t be an option.

As you can see from the screenshot below, I have the “hide empty terms” box checked, but it doesn’t appear to be working. Is there something else I need to do like check the hierarchical box?
