Which search engine do you use?

I use Yandex... maybe because it's set as my default search engine. Although, I have other search engines too... in general, out of all of them, I like it the most, after Rambler and Mail...
Google is better in my opinion, but I use it in extreme cases... to search for something international, rare, and important, and also if I can't find it through Yandex. Usually, it's been songs by lesser-known bands.
