Neo4j按查询顺序排列的性能不佳

我有一个复杂的密码，当我不使用“orderby”时，我会得到一个相当快的响应，但当我使用“orderby”时，它会非常慢。我的order属性（电影的分数，即PageRank算法分数）上有一个b树索引。我加了密码

MATCH (m:Movie)
WHERE m.release > '0' AND m.imdbVoteAverage > 0 AND
CASE WHEN NOT [] = [] THEN any(title in [] WHERE toLower(m.title) CONTAINS title OR toLower(m.originalTitle) CONTAINS title) ELSE TRUE END
WITH m AS m
MATCH (m)-[:HAS_GENRE]->(genre: Genre)
WHERE CASE WHEN NOT ['komedi'] = [] THEN any(genreName in ['komedi'] WHERE toLower(genre.name) CONTAINS genreName) ELSE TRUE END
MATCH (m)<-[acted:ACTED_IN]-(actor: Person)
WHERE CASE WHEN NOT [] = [] THEN any(actorName in [] WHERE toLower(actor.name) CONTAINS actorName) ELSE TRUE END AND
CASE WHEN NOT [] = [] THEN any(characterName in [] WHERE any(cname in acted.characterNames WHERE toLower(cname) CONTAINS characterName)) ELSE TRUE END
MATCH (m) -[:HAS_KEYWORDS]->(keyword: Keyword)
WHERE CASE WHEN NOT [] = [] THEN any(keywordName in [] WHERE toLower(keyword.name) CONTAINS keywordName) ELSE TRUE END
MATCH (m)<-[:PRODUCED]-(producer: Person)
WHERE CASE WHEN NOT [] = [] THEN any(producerName in [] WHERE toLower(producer.name) CONTAINS producerName) ELSE TRUE END
MATCH (m)<-[:DIRECTED]-(director: Person)
WHERE CASE WHEN NOT [] = [] THEN any(directorName in [] WHERE toLower(director.name) CONTAINS directorName) ELSE TRUE END
MATCH (m)<-[:WRITTEN]-(writer: Person)
WHERE CASE WHEN NOT [] = [] THEN any(writerName in [] WHERE toLower(writer.name) CONTAINS writerName) ELSE TRUE END
MATCH (m)<-[:PRODUCED_COMPANY]-(productionCompany: ProductionCompany)
WHERE CASE WHEN NOT [] = [] THEN any(producedCompanyName in [] WHERE toLower(productionCompany.name) CONTAINS producedCompanyName) ELSE TRUE END
RETURN DISTINCT m ORDER BY m.score DESC LIMIT 10 

匹配（m:电影）
其中m.release>0和m.imdbVoteAverage>0和
如果不是[]=[]则任何（在[]中的标题，其中toLower（m.title）包含标题或toLower（m.originaltle）包含标题）否则为真结束
以m为m
匹配（m）-[：具有类型]->（类型：类型）
如果CASE WHEN NOT['komedi']=[]那么任何（在['komedi']中的genreName），其中toLower（genre.name）包含genreName），否则为TRUE END
匹配（m）（关键字：关键字）
其中CASE WHEN NOT[]=[]则any（关键字名称在[]中，其中toLower（keyword.name）包含关键字名称）ELSE TRUE结束
匹配（m）您需要向计划者表明您的m.score字段是数字字段，因此从索引中提取该字段。即
其中m.score>0

您应该在查询计划中看到它

您的查询看起来也非常复杂，而且是生成的。但实际上没有考虑到总是“false”的表达式可以从查询部分中删除，例如，
WHERE not[]=[]
它解决了问题，谢谢。
