You mean in the most efficient way? Currently you'll have to go with a relationship index if you have many edges and would like to do a fast lookup for a relationship between two nodes. You can index relationships just as you do nodes: RelationshipIndex index = graphDb.index().forRelationships( "my-relationships" ); index.add( myRelationship, "myKey", "myValue" ); ... // Either if you query for a specific property: index.get( "myKey", "myValue", startNode, endNode ); // Or if you just query using the nodes index.get( null, null, startNode, endNode ); The other way is to loop relationships from one node and see if the otherNode of those relationships matches. Might be slower though Best, Mattias 2011/2/10 Jose Angel Inda Herrera <jai...@estudiantes.uci.cu> > > hello list, > How to get an edge in the graph (in this case a relationship) having the > two nodes of this relationship, > > thank beforhand > _______________________________________________ > Neo4j mailing list > User@lists.neo4j.org > https://lists.neo4j.org/mailman/listinfo/user > -- Mattias Persson, [matt...@neotechnology.com] Hacker, Neo Technology www.neotechnology.com _______________________________________________ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user _______________________________________________ Neo4j mailing list User@lists.neo4j.org https://lists.neo4j.org/mailman/listinfo/user
