There is also another search engine with similar good privacy rules:
https://ixquick.com/DuckDuckGo is good and has some nice features like typing "!so perl linux" will search stack overflow for perl and linux.
There are many many predefined !bang words.
Disadvantages:
- Just like Google it seems to prefer to put wikipedia entries on top (which I am generally not interested in, I would have searched on Wikipedia myself first)
- It's based on Bing mostly and they are just not as good as Google.
That said, I have used DDG now for almost 2 years and removed Google from all my shortcuts, surely they are doing fine.
