包路径：org.neo4j.graphdb.schema.Schema
类名称：Schema
方法名：indexFor

Schema.indexFor介绍

[英]Returns an IndexCreator where details about the index to create can be specified. When all details have been entered IndexCreator#create()must be called for it to actually be created. Creating an index enables indexing for nodes with the specified label. The index will have the details supplied to the IndexCreator. All existing and all future nodes matching the index definition will be indexed, speeding up future operations.
[中]返回一个IndexCreator，可以在其中指定要创建的索引的详细信息。输入所有详细信息后，必须调用IndexCreator#create（）才能实际创建它。创建索引可以为具有指定标签的节点建立索引。索引将向IndexCreator提供详细信息。所有与索引定义匹配的现有和未来节点都将被索引，从而加快未来的操作。
