Why does split make a mistake?

```
GET /data/_search
    {
      "from": 0,
      "size": 6,
      "query": {
         "function_score": {
             "query": {
        "bool": {

              }
            }
          ]
        }},
            "script_score" : {
                "script" : {

                }
            }
        }

          "_score": {
            "order": "desc"

            "order": "asc"
          }
        }
