Thanks to this post, search exact phrase with relevanssi, I have recently added an exact phrase option to my search box. I have searched as best I can to find which file and/or what to add to my theme functions.php file to customize the search results string Post containing "search terms". If 'exact phrase' is chosen, the string that appears on the search results page is Post containing ""search terms""
I would like to change the quotation marks that appear around the search terms into square brackets. Any ideas about how to do this?
