Relevanssi Not Working At All- Here is my search.php

[ Moved to the Fixing WordPress sub-forum. ]

So I’d love to get Relevanssi working on my site; I’m using the rehub theme. It seems that it’s probably the theme that is preventing it from displaying anything in the search results? If I mistype a word, it just shows the standard message “No products were found matching your selection.” Here is my search.php file. If anyone could help, that would be great.

[ Moderator note: code fixed. Please wrap code in the backtick character or use the code button. ]
