Neo4j - 按多种关系类型匹配

Question

我想通过多种关系类型在实体之间进行匹配。

是否可以说以下查询:

match (Yoav:Person{name:"Yoav"})-[:liked & watched & ... ]->(movie:Movie) return movie

我需要所有关系类型之间的“和”； Yova 喜欢并观看了......一部电影。

Answer 1

是的，您可以执行以下操作:

match (gal:Person{name:"Yoav"})-[:liked|:watched|:other]->(movie:Movie) 
return movie

I need "and" between the relation types.. you gave me an "or"

在这种情况下，您可以执行以下操作:

match (Yoav:Person{name:"Yoav"})-[:liked]->(movie:Movie),
(Yoav)-[:watched]->(movie),
(Yoav)-[:other]->(movie)
return movie
