Currently if I search for a word that shows up in the Product description, then it pulls up some unexpected products because descriptions can have a wide variety of words. How can I exclude words in the Product description in the Search function?
There may be a way to do it with an already published plugin. Your best bet would be to check the WordPress.org plugin repository and see if that is a part of any of the major search plugins like Relevansi or something like that.
Otherwise the search just plugs right into the native WordPress search function so there isn’t anything theme side that we could direct you to.
