First of all, thank you this plugin. It is exactly what I was looking for. Thanks for the good work, Scribu :)
Today I have found some weird behaviour in some scenarios using this plugin.
The first scenario is the following. Once I do a search using these filters and I get the matches, what happens is that the terms in the widget are limited to any matching results on the page, and I can't do a clean search anymore.
For example, I have a few taxonomies: Region, Country and Industry. They all have several terms. Once I choose a region, country and industry and I get the results, the dropdowns in the widget only display a few terms, but not all of the terms for each taxonomy.
The second scenario is when I only select a country, and don't select anything from the rest of the taxonomies. Then, it returns my results, but in the widget all af the dropdowns dissappear except for the one that returned results. So, in this case, I'm left with just the Country dropdown. The rest is all gone.
The third scenario is when my query returns no matches. Then ALL of the dropdowns are completly gone.
I wonder what's happening here, and how to prevent this.
Idealy I want the plugin to allow to do a clean query and show all of the terms and all of the dropdowns at all times. So, that if there are no results, one can continue looking.
Any ideas on what may be going on?
