Support for custom search page

Hello,

Please how can I make your plugin work with this code below

// Change the search results page URL slug
function wpcs_search_url_rewrite_rule() {
  if ( is_search() && !empty( $_GET['s'] ) ) {
    wp_redirect( home_url( '/search/' ) . urlencode( get_query_var( 's' ) ) );
    exit();
  }  
}
add_action( 'template_redirect', 'wpcs_search_url_rewrite_rule' );
