Hello, I have tried to use ACF with taxonomies terms but I have got one problem.
I set up field type = taxonomies and there are only two format of return value: ID or WP_Term.
There is no term value or name. WP search doesn’t find any term by value if I set up WP_Term as a return value. Is there any solution to search post or product by term name from taxonomies in custom fields?
If you are talking about the WP search form, No, you cannot search posts by term name. The built in WP search will not even search posts by term even without ACF. https://wordpress.stackexchange.com/questions/2623/include-custom-taxonomy-term-in-search
