     * 索引 别名 就像一个快捷方式或软连接，可以指向一个或多个索引，也可以给任何需要索引名的 API 使用。别名带给我们极大的灵活性，
     * 比如 我们线上使用一个索引名为index_a的结构，里面有一个类型现在不满足要求，现在需要修改，因为elasticsearch不支持直接修改类型，所以我们必须要重新建立一个新的索引
     * 然后将久索引的数据拷贝过去。 但是如果让新的索引起作用，我们需要要修改引用代码，因为索引名称更换了，但是如果我们一开始创建索引的时候就给索引增加一个别名
     * 使用的时候都是使用index_alis 无论软连接的指向是什么索引，对外暴露的始终都是index_alis
