There are engines I use to see past the useless SEO clickfarms that plague google results:

• https://wiby.me (focuses of non-commercial, lightweight websites. websites can be manually submited. not many results, but usually high quality.)
• https://millionshort.com (Metasearch engine which filters the top 100/1k/10k/100k/1M ranked sites, exposing obscurer sites which may be highly novel)
• https://duckduckgo.com (I’m sure everyone here knows about it, it’s pretty solid. At least it finds forum discussion unlike google.)
