    // The search form relies on control of the redirect destination for its
    // functionality, so we override any static destination set in the request,
    // for example by drupal_access_denied() or drupal_not_found()
    // (see http://drupal.org/node/292565).

        unset($_GET['destination']);
    }
    // Check to see if the form was submitted empty.
    // If it is empty, display an error message.
    // (This method is used instead of setting #required to TRUE for this field
    // because that results in a confusing error message.  It would say a plain
    // "field is required" because the search keywords field has no title.
    // The error message would also complain about a missing #title field.)
