Neo4j：如何匹配关系？

Question

For example: I know a person A who is connected to another person B and person B is connected to person C

How can i show that person A is indirectly connected to person C?

Answer 1

You're question doesn't contain any code/query sample, so I made some assumptions and just give you an example how I should approach this:

MATCH (personA:Person)-[:HAS_FRIEND]->(personB:Person)
WITH personA, personB
OPTIONAL MATCH (personB)-[:HAS_FRIEND]->(personC:Person)
WITH personA, personB, collect(distinct personC) AS friendsOfPersonB
RETURN personA, personB, friendsOfPersonB
