Hi, thanks for your work. I am curious about if I set similarityThreshold very very small and distanceFunction='euclidean'

Let's say, there is no near similar items from ItemA.
Then, what is the output of this specific ItemA? The Algo will output empty and ignore this ItemA?

many thanks

you'll just get an empty collection of neighbours
