Hi Guys, I am aware that Neo4J doesn't have a concept of a bidirectional relationship and I believe that's causing me a problem when using MERGE. Here is my Cypher:
MATCH (fromCard:Card),(toCard:Card) MERGE (fromCard:Card)-[r:DECK_INCIDENCE]->(toCard:Card) SET r.deckCount = coalesce(r.deckCount, 0) +1 So say I have a collection of 4 cards: "Hearts","Diamonds","Clubs","Spades" The first time I create the relationship between Hearts and Diamonds, i.e. Hearts -> Diamonds. However, the next time the cards are in a different order and when I attempt to MERGE Diamonds -> Hearts a new relationship is created because no relationship exists in that direction. This is not what I want, I need to increment the deckCount property on the relationship regardless of the direction and don't want to have to manage two relationships per card. I cannot guarantee the order of cards and in essence I need to model a Bidirectional Relationship. How can I achieve what I need using MERGE?
