Ok I created a navigation menu link to open the mysite/searchKeyword.php file, but searchKeyword.php is available to everyone and there is no way to stop unauthenticated users from searching my site. It happens on UNA too: https://una.io/searchKeyword.php 

I attempted to disable all searches by changing the search files in the root directory, but then the hashtags wouldn't work. There needs to be a way to stop unauthenticated users from searching the site.
