Replace URL query string with slash for a cleaner URL
You can use something like this on your custom module for the redirects with the query strings.

/*
 * custom redirect with query string
 * module implements hook_init()
 */

function MyModule_init() {
  if ($_GET['q'] == 'userguides/contacts/my-first-user-guide/article/referral-partners') {
    drupal_goto('userguides/contacts/my-first-user-guide', array('query' =&gt; array('article' =&gt; 'referral-partners')));
  }
}
