es的索引别名操作

解决方案：
1.设置别名
POST /_aliases
{
  "actions": [
    {
      "add": {
        "index": "scooter_coupon_trans_v1",
        "alias": "scooter_coupon_trans"
      }
    }
  ]
}

查看别名：
scooter_coupon_trans_v1/_alias

查看别名指向哪个索引：
/_alias/scooter_coupon_trans

删除别名：
POST /_aliases
{
  "actions": [
    {
      "remove": {
        "index": "scooter_coupon_trans_v1",
        "alias": "scooter_coupon_trans"
      }
    }
  ]
}
