Russian Yandex

Exceptionally good at finding torrent sites and other piracy outlets, because they aren't working hand-in-glove with American broadcasters to censor and shadowban these links. Google, Bing, DDG, and the other American mainline search sites all focus on feeding end-users into a discrete set of Web2 mega-site sponsors. Yandex uses the older web crawlers and indexing tools, so it gives more honest (abet fuzzier and less reliable) results. And since nobody really gives a shit about Yandex, the efforts to game its algorithm have been comparatively minimal.

Yandex also has the benefit of being relatively English-friendly, while other popular non-English search sites like Baidu, Qwant, and Naver don't cater too quite so freely.
