I tried a few test searches, and didn't seem to get many useful results at all. Searching for [debian] did not produce any debian.org results anywhere on the first page. Similarly, searching for [google] did not produce google.com (or any other google domain) on the first page. Searching for [lwn] produced one random LWN comment, but nothing else. Searching for [linux] produced a page full of links to the Wikipedia articles on Linux in numerous different languages, in no sensible order.
