Neo4j中的apoc.cypher.mapParallel2未给出预期结果

我有以下疑问

MATCH (e) WHERE SIZE((e:Customer)<-[:Transaction]-()) <> 0
AND SIZE(()<-[:Transaction]-(e)) <> 0
MATCH path = (e)-[:Transaction*..10]-(e) return path

---

MATCH（e）WHERE SIZE（（e:Customer）这个同样更高效的查询是否适合您

MATCH (e:Customer) 
WHERE (e)<-[:Transaction]-() AND ()<-[:Transaction]-(e)
WITH collect(e) AS users
CALL apoc.cypher.mapParallel2(
  "match (_)-[:Transaction*..10]->(_) return _.ID as ll",
  {},users,10) YIELD value
RETURN value.ll

匹配（e:客户）
其中（e）否，仍然不产生任何结果。
MATCH (e:Customer) 
WHERE (e)<-[:Transaction]-() AND ()<-[:Transaction]-(e)
WITH collect(e) AS users
CALL apoc.cypher.mapParallel2(
  "match (_)-[:Transaction*..10]->(_) return _.ID as ll",
  {},users,10) YIELD value
RETURN value.ll
