我遇到的问题是Neo4J-entreprise版本2.2.0RC-01。 我们的一个关系有一个名为Search_Field的属性。 此属性是AutoIndex（在neo4j-server.properties文件中配置）并且是全文（lucene）。 当我们使用与前一个完全相同的值更新此类属性时（例如：Search_Field =＆＃39; ABC＆＃39;） 当我们这样做时：
START r1=relationship(137)
SET r1.Search_Field = 'ABC'
RETURN r1
发生此错误：
java.lang.Long cannot be cast to org.neo4j.index.impl.lucene.RelationshipId
如果我们更改了值（BCE而不是ABC），它就可以了！ 如果我们在节点的属性上也做同样的事情，也就是AutoIndex - 全文 - lucene，它就可以了，没有问题。
是否有人遇到类似的问题？
这是堆栈跟踪：

答案 0 :(得分：0)
我有同样的问题...... :(不能用长值索引关系属性。（发布Neo4j-2.2.0）
解决方法：
a）禁用自动索引
b）使用强制转换为字符串更新关系属性：
match ()-[r]-() set r.prop = toString(r.prop);
c）启用自动索引
d）建立关系属性索引：
match ()-[r]-() set r.prop = r.prop;
答案 1 :(得分：-1)
在尝试简单执行时也一样： match（） - [n] - （）set n.objectId1 =＆＃39; a12＆＃39;
当objectId1上有自动索引时。
java.lang.Long无法强制转换为org.neo4j.index.impl.lucene.RelationshipId Neo.DatabaseError.Statement.ExecutionFailure
