I'm just a week into using it, but one of the things I've noticed is that for technical queries official docs are ranked a lot higher than random blogs and those sites that just repackage content they scraped from Stack Overflow.

I don't know if they're putting a finger on the scale, or maybe they're just doing the original Google thing of ranking sites that seem to be where the search terminates higher, but it's good.

You can bump individual sites up and down in priority for your account. Hover over the shield to the right of each result and click ‘raise’, ‘lower’ etc

It appears you can as one commenter who uses the search engine states in one of the comments.
