Here is something that I did in yahoo pipes. It shows how that using a query from the user you can search multiple websites. It accomplishes this by sending a query to a few torrent search engines (mininova, isohunt, btjunkie, sumotorrent). This is accomplished by the URL builder module for each website. Then it fetches the RSS feed from all of those websites and puts them into a combined RSS feed (Fetch Feed Module) . The last two things that it does is it filters all of the unique RSS feeds and then sorts them by item.pubdate so that the latest torrents are found first in the pipe.
