Sort/filter nodes based on relation properties

Question

Given the following graph:

1. How do I get the nodes adjacent to node[5] with weight > 50?
2. How do I get the nodes adjacent to node[5] with label "knows", sorted by weight?

Answer 1

Not sure about Gremlin, but in Cypher it is:

1:

START s=node(5) MATCH s-[r]-f WHERE r.weight > 50 RETURN f

2:

START s=node(5) MATCH s-[r:knows]-f RETURN f ORDER BY r.weight

If you care about the direction of the relationship, put arrows on the relationships, like "s-[]->f" or "s<-[]-f"
