I'm trying to write a book and researching some niche old stuff and trying to extract info from 90s websites (some of the websites are dead and I don't know how to search Internet Archives), and Google Search is becoming hopeless, so I've been switching to yandex.com to find stuff. Even Google Image Search is terrible now and I use TinEye.com and yandex.com for that. I should probably try Bing more as well.
