Hey so, I have been working on a specialized search engine (at least you can think of it in this way). And for me a lot of the gains came because we could structure and restrain the search space in a meaningful way, such that we could build better distance metrics than a pure text search could do.

I wonder what you think about that. Maybe one could submit a code snippet, or mark something as an error, or ask for a refactor of some code. But then again, this gets close to what copilot is doing.
