Yep, ive been using a similar technique for a while.

For example I remember the office xp corp key starts with FM9FY. I dont know the whole number off the top of my head, but typing those 5 chars will return a list of pages, all with that serial number.

And the best part is that the whole number shows in the description so I can avoid visiting the site, hence avoiding all the popups (usually inappropriate) usually associated with warez sites.
