Hi Ernest!
1. Unfortunately, text fields are the more significant concern. The static list to generate a dropdown isn’t a big deal and from the performance perspective is probably a good idea. We’d like to allow a filter for presenters and series names whose dropdowns would look like this:
Null || [Empty]
Presenter One || Presenter One
Presenter Two || Presenter Two
Presenter Three || Presenter Three
The default selection would always be [Empty] which would allow searching across the full post set, but any other selection would offer a filter. I figured this was built into the custom field search so that when the search is triggered if the value selected is equal to “null” it bypasses the filter altogether, otherwise it performs the search as usual with the filter.
