cara rubah ?s= pada submit search wordpress ke /search/

ceritanya biar seo friendly gitu pas submit search permalink nya kan default nya ?s= , biar jadi /search/ maka tambahkan ini di atas <?php get_header(); ?> pada search.php
==============================================
<?php
add_action( 'parse_query', 'my_parse_query');

function my_parse_query()
{
  global $wp_query;

  // redirect
  if(is_search() && $_GET['s'])
  {
    ob_end_clean(); 
    $change = array('+',' ');
    $redirect = '/search/' . str_replace($change, '-' ,$_GET['s']). '';
    header("HTTP/1.1 301 Moved Permanently");
    header("Location: $redirect");
    die;
  }
}
?>
