 * Hi there!
 * Your plugin works well over the whole site – just when displaying the search 
   results page, it produces a warning. Please see following links:

 * Hi [@zweigrafiker](https://wordpress.org/support/users/zweigrafiker/)
 * Thank you for using Filter Everything plugin and for your bugreport.
 * This bug is already solved for the next pugin version, which will be available
   in 5-7 days I think. But if you want to fix it right now you can replace in the
   file `/wp-content/plugins/filter-everything/src/Admin/FilterSet.php` line 417
   this code string
 *     ```wp-block-code
       $key = 'set_' . $post_type;
       ```
   
 * with this one
 *     ```wp-block-code
       if ( is_array( $post_type ) ) {
           $post_type = implode( "_", $post_type );
       }
   
       $key = 'set_' . $post_type;
       ```
   
 * You can do it via /wp-admin -> Plugins -> Plugin file editor.
 * Please, let me know if it was helpful for you.

   If it is possible I would be thankful for a positive review about the plugin
   here on WordPress.org – [https://wordpress.org/support/plugin/filter-everything/reviews/](https://wordpress.org/support/plugin/filter-everything/reviews/)
   This will help me to populate the plugin.
 * Thank you in advance!
