Search engines that are not Google

Lately I've been finding it quite difficult to actually get good results from most search engines, hence after a while I'd often end up back on "do some evil" Google search engine page. After experimenting with other search engines like Ixquick (very good on privacy) and Clusty (they changed their name :/ but I like the idea of clustering results) I was still hungry. And then I found DuckDuckGo, very nice and clean interface, works with https (as the link shows) and gives results in https when possible. It has too many features for me to write about, go and look around in the options and such.
