Sounds like the same could be done with a slightly longer, but far more readable date + sequential identifier. Such as `YY-xxx` or `YYMM-xxx`.
Or just YYMMDD, since there's typically not all that many things you create in one day, so you can just browse among the search hits and it'll be obvious which of the hits you had in mind.
This looks fine, but then if I rename the note, the code changes, invalidating all the hand-written notes links. So it feels unpractical. I would still prefer to encode the creation timestamp and put it in the title/filename/property. At least this would be fixed.
