1. Searx is a metaengine that combines results from different engines and can be used to search directly for files, making it great for piracy and finding very specific things, it's great. It works similarly to nitter and has multiple slightly different instances catalogued on searx.space, so, unlike regular search engines, so you'd have to try out a couple to find one that works the best for you. Highly recommended.
2. Didn't expect to say that, since it has always kinda been a "we have Google at home" engine, but Yandex has probably become better and more accurate than Google in recent years, go try it out (after you manage to disable that GO DOWNLOAD OUR BROWSER RIGHT NOW notification that pops out after every search).
3. wiby.org is not really a conventional search engine, but a kind of archive for personal websites that used to be common in the early years of the Internet and are still functioning. Open it and click the "surprise me" button a dozen times, I guarantee that you won't regret it.
