Neo4j APOC触发器,手动索引-小写属性值

我创建了以下Neo4j APOC触发器,它将节点属性添加到手动索引中:

CALL apoc.trigger.add('CREATE_NODES_TRIGGER', "UNWIND {createdNodes} AS n 
WITH n WHERE labels(n)[1] IN ['Title','Name','Character'] 
CALL apoc.index.addNodeByName(labels(n)[1], n, keys(n)) 
RETURN true", {phase:'before'})

当我执行以下查询时:

CALL apoc.index.nodes('Character','name:An*') YIELD node AS c, weight 
RETURN c.name, weight LIMIT 10

它正确返回数据:

c.name  weight
"Annette Porter"    1.0
"Anke Bauernfeind"  1.0
"Angel's Henchman"  1.0
"Anna Slovatzka Marshall"   1.0
"Andrew Horvath"    1.0
"Angela Somes"  1.0
"An-Soo 'Alison' Kim"   1.0
"Annette Holman"    1.0
"Anita Wilcox"  1.0
"Anna Cerdick"  1.0

name:an*

CALL apoc.index.nodes('Character','name:an*') YIELD node AS c, weight 
RETURN c.name, weight LIMIT 10

结果为空。

我认为我应该在将属性值添加到索引之前将其小写。我说得对吗?

如果是这样,请您帮助改进触发器以使属性值小写:

呼叫apoc.trigger.add('CREATE_NODES_TRIGGER',“展开{createdNodes}为n”
呼叫apoc.index.addNodeByName(标签(n)[1],n,键(n))

或者,请提出另一种解决这个问题的方法。谢谢!

我在neo4j.conf中找到了以下属性:

apoc.autoIndex.enabled=true

并将所有节点添加到索引中:

CALL apoc.index.addAllNodes('movies',{
  Title: ["primaryTitle", "originalTitle"],
  Name:  ["primaryName"],
  Character: ["name"]}, {autoUpdate:true})

所以,现在我有一个问题:威尔 apoc.autoIndex.enabled=true apoc.index.addAllNodes Title , Name 和 Character 节点也到索引?
