add new permalink structure from dynamic page

Only way I knowit to do this it’s using this function:

/*
 * Redirects search results from /?s=query to /search/query/, converts %20 to +
 * @link http://txfx.net/wordpress-plugins/nice-search/
 * =======================================  */
function search_redirect() {
  if (is_search() && strpos($_SERVER['REQUEST_URI'], '/wp-admin/') === false && strpos($_SERVER['REQUEST_URI'], '/find/') === false) {
    wp_redirect(home_url('/finde/' . str_replace(array(' ', '%20'), array('+', '+'), urlencode(get_query_var('s')))), 301);
    exit();
  }
}
add_action('template_redirect', 'search_redirect');

It’s this you wanna do?
