Neo4j How to check the relationships for an specific node

I'm reading about relationships and how I can obtain the relations of each individual node.

Just now, I have a node A with relation [:MATCH] with a node B, also I have the nodeC and the node D.

I could have more node relations with [:MATCH] in other nodes.

How I can obtain only relations of an specific node?

To see an specific relation you can use:

MATCH (p:Person)-[r:WORKS_FOR]->(c:Company)
WHERE p.name = "Bob"
RETURN r;

But, If you need see a Bidirectional relation, you can use:

MATCH (p:Person)-[r:WORKS_FOR]-(c:Person)
WHERE p.email= "[email protected]"
RETURN r;

When you can use it?, For example, if you have a friend you can say: John is Friend of Mary, and Mary is John's Friend. Add two relationships is a bad pattern in Neo4J, but you can use - wihout the symbol > to not specify direction of the relationship.

With Cypher you can bind variables to relationships in a pattern. For example:

MATCH (p:Person)-[r:WORKS_FOR]->(c:Company)
WHERE p.name = "Bob"
RETURN r;

Will bind any :WORKS_FOR relationships to the variable r for the Person node with name property "Bob".
