I remember it used to be easy for me to find obscure things on google using the advanced features. As they "improved" Google by giving it better results for the average user with sort of a "dumbed down" kind of feel, my ability to do that went way down. A few years after that, the personalized results started to get really really good, around 2014-2015 or so. Since then, it's gotten bad again, and I'm not sure why, but I suspect it has to do with $$. Basically it started with the Wikipedia article not being the first result and has continued to devolve. I never did recover the ability to get nuanced searches like I used to. It's kind of just a luck thing now. Although I actually am having better luck with duckduckgo now.
