elasticsearch带路由删除

今天测试代码，发现 我的文档带着路由的时候，删除带不带路由都失败
 
GET /tk_appsearch_good_1/ty_good/943749480862326784_37?routing=37  这样得到文档，

"_id": "943749480862326784_37",

"_version": 1,

"_routing": "37",

"found": true,

再删除这个文档：
DELETE /alia_appsearch_good_1/ty_good/943749480862326784_37?routing=37
 
提示没找到

{

   "found": false,

   "_index": "tk_appsearch_good_1-20171223",

   "_type": "ty_good",

   "_id": "943749480862326784_37",

   "_version": 1,

   "_shards": {

      "total": 2,

      "successful": 2,

      "failed": 0

   }

}

 
求解
