Global search is provided by YouTube, so I can't guarantee anything.

I could add some local filters if necessary, but doesn't YouTube already provide its own filters based on when the video was published? Cathode exposes these.

Interesting. I consciously, actively smack YT with a rolled-up newspaper in the form of 'never recommend this channel' specifically to make it only recommend me stuff that I've already watched, and not try to pipeline me in some algorithmic direction such has happened at some periods. I don't think I have to draw people a picture here.

I've never imagined actually wanting an algorithm that would find things I'd actually like, having been burned so badly by 'algorithm that finds things it wants to get me to like'. Are you sure you want an algorithm to do that?
