I don’t mean like a closed algorithm.

I mean like a search engine I could tell: I want you to downgrade [healthline.com] and push it lower down in results. Or I want you to “upgrade” [arstechnica] and show it higher in results.

etc

Do you know about a private customizable search engine? I would like to hint the search engine about what search results I like without specifying them on every single query.

For instance when need to search up some programming documentation almost always there are some blogs in the search results meanwhile I'm always looking for the official documentation. I want to go to settings and specify something like

+ official documentation
- blog

and every single time I search something up I get less noise. Also being able to block some domains like

geekforgeeks.org
learn.microsoft.com

would also be nice. In case I get annoyed by some domain that have a lot of ads and information at the very bottom.

see how it goes ..
