Thanks for replying Andrew. “Custom” taxonomies probably wasn’t the way to phrase it, I simply mean taxonomies that I would create.
So, for example if there were a custom post type of “Cars” there may be different taxonomies such as “Price” “Model” or “Color”. I am looking for a similar functionality of the FACETED SEARCH plugin above (cheers to you on developing the plugin) that uses taxonomies instead of categories or tags.
