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.

Afaict, it searches only sites where it is installed. Presumably debian.org hasn't installed it. (So, no, it won't be a google killer. But there may still be a market for it, if it does local searches fast and well.)
