This is a bit beyond me. Can you help me in how to implement the "wpv_filter_query" hook? Also, it sounds like this becomes a two part filter…Is the logic like this?
Filter 1: Show recipes that have these taxonomies, and where the field "ingredients" contains XXXX.
FIlter 2: From the filter 1 results, exclude recipes where the field "ingredients" contains YYYY.
Thanks…
