Question

我有一个EntityNode类定义如下

@NodeEntity
@TypeAlias("Entity")
public class EntityNode {

    @GraphId
    private Long id;

    @Indexed(indexName="entity_name_ft", indexType=IndexType.FULLTEXT)
    private String name;

我还有很多其他域对象用@NodeEntity和@TypeAlias（...）注释（@TypeAlias（“Document”），@ TypeAlias（“UrlVisit”）等...）

插入一些数据后，我运行此查询：

start n=node:entity_name_ft('*:*') return n.name, n.type, labels(n);

我还得到的节点不是EntityNode类型，而是由索引'entity_name_ft'返回：

我只在EntityNode类中使用索引名'entity_name_ft'，但正如您在上面看到的那样，Cypher查询还返回Document，DocumentCategory，UrlVisits等类型的节点......

我只通过SDN进行插入操作，而不是手动索引Cypher控制台中的节点。

有没有人遇到过这种行为？请有人解释一下。
