Производительность мелодии следующего neo4j CQL

Я все еще новичок в neo4j. Может кто-нибудь помочь мне настроить производительность ниже CQL? 

WITH apoc.date.parse("2020-04-20",'d',('yyyy-MM-dd')) AS a, apoc.date.parse("2020-04-20",'d',('yyyy-MM-dd')) AS b
MATCH (x:VW_OrderxAttributes_ZSMART_LOTTE)
WHERE a <= apoc.date.parse(x.Zsmart_Lotte_timestamp,'d',('yyyy-MM-dd HH:mm:ss')) <= b
WITH a, b, COLLECT(x.Zsmart_Lotte_OrderID) AS X
MATCH (y:VW_OrderXAttributes_EAI_LOTTE) 
WHERE a <= apoc.date.parse(y.EAI_LOTTE_Timestamp,'d',('yyyy-MM-dd HH:mm:ss')) <= b
WITH X, COLLECT(y.EAI_LOTTE_OrderID) AS Y
UNWIND apoc.coll.disjunction(X,Y) AS XX
RETURN XX;

Я также создал необходимые индексы, надеясь улучшить производительность, но не так много улучшений.

Ниже это ПРОФИЛЬ запроса. Я заметил, что dbhits очень высокий.
