How will I know, if two nodes are somehow connected in Cypher Neo4j -

i have graph depicts node , relationships, entity - references - entity.

i want list containing source entity , connected entity these 2 entities not directly connected connected somehow.

for example : - references -b , c - references - a, d - references - c. in case, want cypher qry return d - references - a.

the output :

a-b

c-a

d-c

c-b

d-a

d-b

cypher pattern matching in graphs. pattern interested in cover not a-b a-c-d. can using variable length match, e.g.:

match (n)-[*]-(m) return n.name, m.name 

this assumes there name property on nodes, can returned. change other relevant property, or return n, m if you're using browser visualization.

note match relationships regardless of direction, means you'll both a-d , d-a in result (and every other combination). if want match 1 direction, use:

match (n)-[*]->(m) return n.name, m.name 

be careful these approaches - in small graphs, end matching huge number of combinations , cause neo4j, or application, die (due memory exhaustion, etc).
