Disabling WordPress search can be a practical decision for certain websites, helping streamline the user experience and potentially improve performance. By following these steps to modify your theme’s functions.php file, you can easily disable the search functionality without the need for additional plugins. Just remember to create a child theme to ensure that your changes remain intact through theme updates, and always make backups before making any modifications to your WordPress files.
