neo4j--使用索引

1.使用关键字INDEX ON为节点的属性name创建一个普通的索引

CREATE INDEX ON :Person(name)

输出：

Added 1 index, completed after 46 ms.

2.使用索引来查询

MATCH (n:Person) WHERE n.name IN ["a","b"] RETURN n as Person

得到图：

3.显式使用索引查询

MATCH(n:Person)

USING INDEX n:Person(name)

WHERE n.name = 'a'

RETURN n as Person

4.用DROP关键字删除一个已经存在的索引

DROP INDEX ON :Person(name)

Removed 1 index, completed after 1 ms.
