You might be able to reference PCORnet documents for this since their tag filter is working as expected.

The default options for the hierarchical search filter facet doesn't support this and I would probably have to intervene at the Java level or the Angular level.

I'm going to close this issue for now, feel free to reopen it as a feature request later, should you want to do this.

Okay, so I think I understand why this is the way that it is. It's definitely not a bug nor is it ideal, but I think I can live with it. I'm going to close this ticket since I don't think it's worth fixing when we have other things to address.
