He Ernest, I will explain my situation so you can suggest me the best solution.
I have CPT with CF and I need to select similar CPT based on different CF (one search instance for CF).
CFs cointains mostly only one value, so for example, I need to show all the items produced in 2007 that has a specific relevant CF value (that I choose in advance) near the one of the current_post (i.e. item smaller than 50 cm)
What could you suggest to achieve this? From your words it seems to me that Ajax Search pro is more suitable.
Kind regards
Lorenzo
