I am trying to limit the number of related nodes in my result per label. Let's say I have a node type A that is related to nodes with different labels (X, Y, Z, etc.). (a:A)-[:RELATED_TO]->(b), here b can have either one of the (X, Y, Z, etc.) labels...

Oh okay. In that case, it's possible that it might return 10 nodes of 'lbl1' and 0 nodes of 'lbl2'. My goal is to get at most 5 nodes for each label.
