Russia has long been a haven for digital piracy and Yandex doesn't block pirate results at all. When I noticed that duckduckgo began quietly censoring some pirate sites I frequented, I ditched it for those purposes.

Yandex is good. Sometimes Qwant.com and Metager.org will find things, too. When Google/Bing/Yahoo/Startpage, etc., don't find what you're looking for, just try search engines based in other countries. Russia/Yandex probably cares less about western DRM than Qwant/France and Metager/Germany. Incidentally, if you open a VK (aka Vkontakte, Russian Facebook) account, you can also open a mail.ru (part of VK) account. Don't forget to set the UI language to something you understand :)
