我无法在Elasticsearch中加载数据

Question

当我使用以下命令行检查状态时，我可以连接到Elasticsearch但无法加载数据：

curl -XGET 'http://localhost:9200/_status'

我收到此消息错误：

{
  "error":{
    "root_cause":[
      {
        "type":"invalid_index_name_exception",
        "reason":"Invalid index name [_status], must not start with '_'.",
        "index_uuid":"_na_",
        "index":"_status"
      }
    ],
    "type":"invalid_index_name_exception",
    "reason":"Invalid index name [_status], must not start with '_'.",
    "index_uuid":"_na_",
    "index":"_status"
  },
  "status":400
}

您能帮我解决这个问题吗？
