FWIW, I've gotten in the habit of using Zotero (https://www.zotero.org/) with a browser extension to do this. If I read something that I think I might want to reference later, I just hit an extension button and it gets slurped into Zotero with a bunch of information indexed for retrieval later.

How much better is that than safari export-to-pdf and spotlight?

Different, not strictly better. Zotero saves a SingleFile html snapshot and will save the original URL and extracted metadata in its database, which is handy if you use Zotero anyway, but unnecessary if you just want to save text. Additionally you'd need to use Zotero to search it instead of Spotlight.

FWIW AnyBox also will save SingleFile archives and make them searchable to spotlight. Big fan.

Why not just use your browser history?

Needle in a haystack when you’ve opened and closed several hundred tabs and you’re trying to find some random fact you ran across a week or two ago.

My browser history seems to work fine for this.

Recording everything on the screen for this use case is completely absurd.
