It is a continually improving experience, so if that was a while ago, it may be worth another shot. If not, sorry to hear that--but I'd appreciate knowing what types of searches weren't working for you, or better yet the actual searches. You can click 'Give Feedback' on any page (bottom right corner).
Not sure if it is a bug or feature, but searching my domain with and without "www" produced different results. I expected actual website to be the first in both cases.
