I think it works: https://www.google.com/search?q=site:gu.com
That gives me 1,150,000 hits. A search for "gu.com" on Hacker News gives just one page of results, though.

Yes, Google indexed many gu.com site hits, so then I believe there must have been a link to those pages somewhere and sometime which the Google crawler found. But searching for those short gu.com URLs now shows no external page hits on Google. (try searching for "gu.com/p/3menc" or "gu.com/p/cqekc" for instance)
