    <p>Hello,</p>
    <p>to have full flexibility here I am thinking of adding a new
      module parameter to set the order-by string when the
      retrieve_order=1, as it may be different for various db
      connectors. The default will be 'priority', which is what is done
      right now.</p>
    <p>That will practically cover also the case of retrieve_order=0,
      where the order by is done on received_time, but for backwards
      compatibility I think it should stay there.</p>
    Cheers,<br>
    Daniel<br>
