Ok, why do you think symbol search can't be integrated in the current codesearch? That's what Amir was proposing. Sadly I don't think much of the current code of ClassCrawler can be reused for that goal, and it's a pity.

It could be integrated with the UI, but would require a very different backend.

I very much like Kunal's suggestion about LSIF. I'll reply to his mail.
