  I have a custom post type with a acf field ‘featured’. If this field is ‘true’ I want the relevant posts to show sticky at the top of search results in a RANDOM order.
  The rest of the results should be show randomly below the ‘featured’ results.

  I have the following code to show the search results randomly:

  add_filter('posts_orderby', 'edit_posts_orderby');
  function edit_posts_orderby($orderby_statement) {
  if(!is_admin()')) {
  
      $seed = $_SESSION['seed'];
      if (empty($seed)) {
        $seed = rand();
        $_SESSION['seed'] = $seed;
      }
     $orderby_statement = 'RAND('.$seed.')';
    }
     return $orderby_statement;
  }

  I want to add to it somehow the above conditions I described.
  get_post_meta( $hit->ID, "_featured", true );
  how do I do this?
