title: Ignore URLs in robot.txt with specific parameters?
body: <p>I would like Google to ignore URLs like this:</p>
  <p><code>http://www.mydomain.example/new-printers?dir=asc&amp;order=price&amp;p=3</code></p>
  <p>In other words, all the URLs that have the parameters <code>dir</code>, <code>order</code> and <code>price</code> should be ignored. How do I do so with <code>robots.txt</code>?</p>
