Hello. I have a question about MERGE.
If an empty graph is given and process a MERGE clause with a bidirectional relationship, According to the manual(link <https://neo4j.com/docs/developer-manual/current/cypher/clauses/merge/#merge-merge-on-an-undirected-relationship>), "MERGE can also be used with an undirected relationship. When it needs to create a new one, it will pick a direction." Query CREATE (a {name: 'a'}), (b {name: 'b'}) MERGE (a)-[r:KNOWS]-(b) Q1) How is the direction determined? Q2) Why not create two relationships for bi-directions(incoming and outgoing)? Thanks. -- You received this message because you are subscribed to the Google Groups "Neo4j" group.
