I have created several instances of the search and two have to search in taxonomies titles but they are not working well. If you access our site and look at the search engine named “Marcas” you will see that it is configured to search in the custom taxonomy product_brand but no results appear.
What do I have to do to solve this problem?
Thank you, it is okay now. Can you please try turning off WPML compatibility: https://i.imgur.com/mjDhLk5.png
I think the taxonomies may not be translated, so that might be preventing them from displaying.
