       function search_filter($query) {
   
       	if (is_search()) {
       		$query->set('post_parent__not_in', array(560));
       		$query->set('posts_per_page', -1);
       	}
   
       	return $query;
       }
   
       add_action( 'pre_get_posts', 'search_filter' );
       ```
   
 * File function.php
 * Nothing happens, the changes are not present. What could be the problem?
    If 
   you insert exit() in check it works.
