Neo4j Cypher 匹配 AND 与 OR

Question

我有以下 Cypher 查询：

MATCH (childD:Decision)
MATCH (childD)-[mandatoryCriteriaVote1:HAS_VOTE_ON]->(mandatoryCriteriaId1:Criterion {deleted: false}) WHERE mandatoryCriteriaId1.id = 1 AND mandatoryCriteriaVote1.avgVotesWeight >= 1.0 WITH childD  
MATCH (childD)-[mandatoryCriteriaVote5:HAS_VOTE_ON]->(mandatoryCriteriaId5:Criterion {deleted: false}) WHERE mandatoryCriteriaId5.id = 5 AND mandatoryCriteriaVote5.avgVotesWeight >= 3.0 WITH childD  
RETURN childD

现在查询的以下部分：

MATCH (childD)-[mandatoryCriteriaVote1:HAS_VOTE_ON]->(mandatoryCriteriaId1:Criterion {deleted: false}) WHERE mandatoryCriteriaId1.id = 1 AND mandatoryCriteriaVote1.avgVotesWeight >= 1.0 WITH childD  
MATCH (childD)-[mandatoryCriteriaVote5:HAS_VOTE_ON]->(mandatoryCriteriaId5:Criterion {deleted: false}) WHERE mandatoryCriteriaId5.id = 5 AND mandatoryCriteriaVote5.avgVotesWeight >= 3.0 WITH childD

作为逻辑运算 AND。这意味着 childD 必须满足这两个条件才能 return 编辑到查询结果。

如何重写此查询以使其符合逻辑 OR？

我的意思是 - return 所有 chilD 满足以下任一条件：

MATCH (childD)-[mandatoryCriteriaVote1:HAS_VOTE_ON]->(mandatoryCriteriaId1:Criterion {deleted: false}) WHERE mandatoryCriteriaId1.id = 1 AND mandatoryCriteriaVote1.avgVotesWeight >= 1.0 WITH childD

或

MATCH (childD)-[mandatoryCriteriaVote5:HAS_VOTE_ON]->(mandatoryCriteriaId5:Criterion {deleted: false}) WHERE mandatoryCriteriaId5.id = 5 AND mandatoryCriteriaVote5.avgVotesWeight >= 3.0 WITH childD

Answer 1

您可以通过如下更新得到相同的结果：

MATCH (childD:Decision)
MATCH (childD)-[mandatoryCriteriaVote1:HAS_VOTE_ON]->(mandatoryCriteriaId1:Criterion {deleted: false}) 
WHERE (mandatoryCriteriaId1.id = 1 AND mandatoryCriteriaVote1.avgVotesWeight >= 1.0) 
OR (mandatoryCriteriaId1.id = 5 AND mandatoryCriteriaVote1.avgVotesWeight >= 3.0) 
RETURN childD
