It's been nagging me for some time, Cypher's syntax checking is not what I would like it to be. Sorry about that...

Re: [Neo4j] Cypher: combining results?
I have a very simply graph: UserGroup 2 -[:IS_MEMBER_OF]- UserGroup 1, User 3 UserGroup 1 -[:IS_MEMBER_OF]- User 1, User 2 And I am trying to get all nodes that are on the same level and below the starting point including the starting point. This works for, e.g. User 3, but not for UserGroup2. The cypher is used is the one presented. Since I cannot get the starting point included, I tried to do this combining thing for the further matching. Am 06.11.2011 12:25, schrieb Andres Taylor: On Nov 6, 2011 10:55 AM, D.

Re: [Neo4j] Cypher: combining results?
Andrés, is there an official grammar for e.g. antlr or JavaCC for cypher syntax?
