Elasticsearch 查询嵌套字段，嵌套对象列表中限制只有匹配的才返回结果，怎么写 dsl

Question

存储的数据是

{
  "id" : "xxxxx",
  "model" : "aaacc",
  "product" : "xxxxasdf",
  "idc" : "ccaa",
  "backup" : [
    {
      "id" : 123,
      "type" : "ssh-11",
      "part" : "ssh-12",
    },
    {
      "id" : 456,
      "type" : "ssh-22",
      "part" : "ssh-23",
    }
  ]
}

返回匹配 backup.type:ssh-11 的结果，正常返回会把 backup 列表都带出来。但是希望之返回比例的子项

希望返回

{
  "id" : "xxxxx",
  "model" : "aaacc",
  "product" : "xxxxasdf",
  "idc" : "ccaa",
  "backup" : [
    {
      "id" : 123,
      "type" : "ssh-11",
      "part" : "ssh-12",
    }
  ]
}
