Has anyone got this working with the search query param?
I've had to (unfortunately) make lots of changes to the plugin core to accomodate how I needed it work (different labels other than the taxonomy name, added counts to dropdowns, added 'disabled' via JS when count is 0 as it wasn't hiding 0 count items, added an onChange to dropdowns...).
My remaining task is to add the search param into the initial count result. Sort of an advanced search filtering system I guess.. It's working with the search param in the sense that the page only shows items with that keyword, it's just the counts that are squiffy!
Search 'cloud', url: /?s=cloud
Show the 'drilldown' with counts based on the current search query and ability to drilldown appropriately..
