Finding files on rapidahare, mediafire, megaupload, etc?

I'm trying to find a specific clickbank (non-IM related) product for a friend's dad, but just about every result I can find is a page just spitting back my search terms and surrounding them with ads, or is an affiliate signup link for the file sharing site..

What's the best way to search for a specific product on these types of sites?

(the cb product I'm looking for is an ebook called "power4home" btw.)

megadownload.net = rapidshare + megaupload.

Or just use google:
site:mediafire.com "keywords"

No results.. thanks for letting me find a legit answer, even if it wasn't the one I was looking for!
