Disable Search is a WordPress plugin by coffee2code that disables the search capabilities of WordPress.
Prevents the search form from appearing (if the theme uses the standard get_search_form() function to display the search form).
Disables the search widget.
With or without the search form, the plugin prevents any direct or manual requests by visitors, via either GET or POST requests, from actually returning any search results.
Submitted attempts at a search will be given a 404 File Not Found response, rendered by your sites 404.php template, if present.
