Searx - Self-hosted meta search engine

I've recently started using a self hosted SearXNG instance but I'm still using the search engines enabled by default (google, duckduckgo and qwant). What search engines do you have enabled or which ones do you feel you've gotten the best results with?

I want a search engine that indexes and displays only the sites I ask it to (my bookmarks). I often come across insanely good articles and resources, but because I don’t really need them at that moment, I forget about them and can’t find them when I need them. Maybe there is a search engine at which you can throw good websites you find, and then use if you think you came across it before.

I am not sure if SearX will be able to help here, but I am sure someone will have advice...

Currently I am just storing everything into a Notion database, but then I either have to write down what that website is, or I will never find it.

Thanks and have a great day.
