WP_User_Search has been replaced by WP_U…

WP_User_Search has been replaced by WP_User_Query. WP_User_Search exists, but is deprecated and has been moved to wp-admin/includes/user.php to deprecated.php.

If you were for some reason including wp-admin/includes/user.php and were expecting WP_User_Search, you’ll need to adjust.
