Ask HN: Best search engine alternatives to Google?

I find Google amazing for some kinds of queries, such as directly answering simple factual questions or finding content within a defined domain.

However, for a lot of things it's quite bad. If I want to find a good website for some use-case (as opposed to directly finding information inside a page), or if I want anything where there might be a commercial interest in ~~lying~~ advertising to me, Google is truly awful.

It's also, obviously, very bad for privacy.

Surely there are a bunch of interesting new search engines popping up given the recent deep learning explosion? What interesting alternatives have you discovered?
