1. Find all the incoming relationships of a node.

MATCH ()-[r]->(n)
WHERE ID(n) = <节点ID>
RETURN r

1. Retrieve all relationships of a node, including both out-degree and in-degree.

MATCH (n)-[r]-()
WHERE ID(n) = <节点ID>
RETURN r

1. Search for relationships of a specified type in the node.

MATCH (n)-[r:关系类型]->()
WHERE ID(n) = <节点ID>
RETURN r

Please note that the in the above query should be replaced with the actual ID of the node.
