    It is impossible to prohibit indexing all links that have mod=order parameters.

    • and how can I prevent indexing of such links? - Yoharny Babay
    • Register all links. - Oleg

    Yandex will understand the star in Disallow

    Google and some others too

    Google, Bing, Yahoo, and Ask for a path of values

      It is not very clear what links should be prohibited. If you want to block links like

      .../index.php?sdfsdfmod=ordersadfsdf

      then such a rule should cut them off. You can check this in the tools for webmasters Google and Yandex.
