Is there a way to link to another View that displays search results without having to use a querystring? For example, I know that I can do the following:

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Index(string txtOrderNumber)
{
    return RedirectToAction("OrderLookup", new { controller = "Report", id = txtOrderNumber });            
}

But, let's say that I only want to use a hyperlink (a hyperlink with the Order Number) and not a form post. How can I route to the result View without using a querystring? many thanks.
