问题 Usually I can find everything I need already on SO but not this time. I'm looking for a very simple way to exclude labels, for example (pseudo code) : match (n) where n not in (Label1, Label2) return n Sorry about crappy query. In short I have labels x,y,z and I want to return all of them apart from z. Thnx! 回答1: This should do it: MATCH (n) WHERE NOT n:Label1 AND NOT n:Label2 RETURN n; 来源： https://stackoverflow.com/questions/32817075/excluding-label-names-in-simple-neo4j-query

How to structure a graph database to support 3-way relationships?

问题 I've been trying to figure out a database backend for a personal webapp I've been working on. Due to the flexibility that I require in the data, a relational database isn't feasible and some form of document storage is likely. When I learned about graph databases, I felt that this would be perfect. However, I've run into someone of an issue: I need to be able to define a 3-way relationship in some way. I haven't decided on a database yet, but I've been tinkering with Neo4j, so I'll use Cypher
