Okay so you need to look at the search engine's querystring (if it even has
one).  In Google's case:

You may have a start URL of
<http://www.google.com/search?q=tasmania>

Then you will notice that each page has this parameter:
start=XX

So in your scan rules (filters):

-*
+www.google.com/search?*q=*&start=10*
+www.google.com/search?*q=*&start=20*

and add however many pages you want.  Keep in mind that your URL may be
slightly different - have different page count, etc - so you would need to
tailor to suit.
