To make Scroogle Scraper a Search Provider in Internet Explorer so the search feature uses it:
1) Open a new IE window or tab
2) Go to this address: http://www.microsoft.com/windows/ie/searchguide
3) In the Create Your Own section of the page, enter this address (copy and paste) in the first box: http://www.scroogle.org/cgi-bin/nbbw.cgi?Gw=TEST&n=1
4) In the second box, give it the name "Scroogle Scraper"
5) Hit the Install button
6) In the window that pops up, you can optionally check the box to make it your default search provider
With the steps above, searches will have 100 results per page. You can adjust the number of search results per page to 20 by changing the address in step 3 so n=2 or 50 per page using n=5.
