I would say this needs a list of indexed repos and mainly an explanation of how it exactly works to be usable (how's the index build and how often it's refreshed, what types of files are being indexed, etc.). Otherwise, there's no much value in searching in an unknown data, is it?

Anyway, to not only criticize, good job! It's definitely one of GitHub's missing features. And I can imagine it's not an easy job to build something like that. But as I wrote, it really has to be well explained to be actually usable.

So you know exactly how Google's index works?

I think "best effort", whatever it is, is useful even if I don't know the specifics of what it captures or misses. As long as it returns useful results.
