Elasticsearch：嵌套映射会在搜索时抛出错误

Question

以下快照不言自明，但这就是我要做的事情。我有一个双嵌套字段 stream.tagging.tag ，我用新的映射重新创建了我的索引。但是当我进行搜索时，ES无法找到内部嵌套字段的路径。

                  },
                  "tag": {
                    "type": "string",

                    "store": true
                  }
                }
              }
            }
          }
        }
      }
    }
  }
}

查询中的嵌套路径不正确。

{
 "query": {
    "nested": {
        "path": "stream",
        "query": {
            "nested": {
                "path": "stream.tagging",
                "query": {
                    "bool": {
                        "must": {
                            "match": {
                                "stream.tagging.tag": "product"
                            }
                        }
                    }
                }
            }
        }
    }
  }
}
