I am trying to:
Use Relevanssi to allow searches for posts based on taxonomy terms
Link to a page where the issue can be seen: hidden link
I have placed a WP Views Filter widget on the page, but it appears that Toolset is not using Relevanssi for searching. Rather it seems to be using the default WordPress search. It will not find any posts based on taxonomy terms for that post. Rather, it seems to be only using the post title.
In order to verify this theory, I placed a regular WordPress search widget on the page, in addition to a WP Views Filter widget. I have a taxonomy called "Product Tags" for a custom post type called "Products". I have three Product posts that have a Product Tags term called "breakfast". If I search for "breakfast" using the regular WordPress widget, it shows me all three of posts that have "breakfast" as a taxonomy term. However, if I search for "breakfast" using WP Views Filter widget, all I get is "No items found". In other words, the WordPress search widget appears to be using Relevanssi, but the Toolset WP Views Filter widget does not.
As an additional test, if I do a search using the WordPress widget, I find that the counters increment on my Relevanssi User Searches Dashboard page. However, if I do the same search using the WP Views Filter widget, the counters do not increment.
What can I do to make Toolset use Relevanssi instead of the normal WordPress search?
This could be that your search field is still only set for Post Title. What you can do is to remove the search field from the view and it should prompt to remove the query filter. Then re-add the search field then ensure the option that includes the custom field is selected.
Thanks for your help, Shane. That was, indeed, the problem. I had to set the search filter for Title, Body, and Custom Fields. After that I was able to successfully search by taxonomy.
