this is the classic option then, where scaling doesn’t change much - you take the universe of one and hope the other one will have stuff in that zone. I tried to explain that clearly here:
In other words: in your corpus has stuff between -100 and 100 and you scale it 0-1, then you enter a target that wiggles between -200 and -100, it will scale to -0.5 to 0 and you will get no match other than 0 as the nearest neighbour. does it make sense?
