For what it's worth, I know someone who started working at GitHub early this year to "make search not suck". So this might be an early indicator of things to come.
Let's hope it will improve at least when searching on a single repo. That I can easily emulate locally though by using ripgrep. Yes, ripgrep gives better results than Github's search :).
Emulating the "which projects use my library" feature of Github is harder though.
