Sometimes you may not want to show your users your full BuddyPress members directory, but only show the results of their searches.

BP Profile Search 5.8.1 allows you to choose this option if you need it. To do so, you can add this line of code to your bp-custom.php file or to your code snippets plugin:

add_filter ('bps_hide_directory', '__return_true');

Thanks to dominik for suggesting the idea and the code!
