I just tried a few queries related to rust and it's library rocket. I got only useless results on the first page and didn't check further. I'm guessing that's because it doesn't index docs.rs and the rust forum. Both incredibly important for Rust development. So as long as this engine doesn't also index most programming related forums, I won't be able to use it effectively, even though I really would like to. The concept of limiting the scope to just a few websites sounds really interesting, though. I think I will take this idea and build a little thing on top of google to implement that site filtering on my queries.
