There is always emacs with org-roam.

Org-roam is kind of a wiki, you write your notes with all the formatting power of an org-file and you can link to other notes you have written.

Of course everything is searchable, with tags, without tags, however you want.

BUT: it takes time to get used to the shortcuts, and it takes a lot of time to configure everything how you like it.

The result is worth it.
