Which search engine do you use?

I use Google as my search engine; in my opinion, it finds various types of information more accurately (I mainly look for text-based information). I also have Rambler and Mail.ru bookmarked, but I only read news on them. I haven't found anything interesting for myself on Yandex, and I've never used other search engines. My email is Gmail, and I haven't noticed any glitches (I use the built-in Opera client).
