I think I basically get the idea, what kind of database are you using? Recoll sounds like a good idea, but I'm also thinking about how I might also make this public-ish.

(i.e. I teach in college and would love to have a centralized way to store and search all my assigned readings, which are most often webpages)

Each html page is processed by (1) getting url, title, time saved (this is under-rated as approximate time of saving is useful if you want to rediscover) and then (2) taking a screenshot and finally (3) extracting text with readability.js and hopefully doing some keyword analysis.

Right now it is stored in a local SQLite Database, although the article content is stored in text files. For search, I can use ripgrep to look through the associated text files.

The eventual goal is to create a flask app which will allow for interactive management of the bookmarks (tagging, searching). I've already got static generation of bookmarks.

Then add a search engine over that, for 'what was that article about long term effects of DDT on ecosystems I was reading a long time ago?' queries.

And you get a memex - a way to outsource part of the brain to a computer :).
