Inside DuckDuckGo, Google's Tiniest, Fiercest Competitor
Duck duck is barely usable ... but they don't spy on you.
The !g and !b commands make it my first choice.   If the results aren't getting what you want, try the search on google or bing. IF you don't mind Sergy Brin or Bill Gates tracking you.I still think there's room for a search engine that supports boolean(ish?) operations like AND, OR , NOT and NEAR.  Providing links directly to the source and not a redirect to the search engine company would be a really good thing.A cookie-less search engine would be double plus good.
