我使用function_score在elasticsearch上运行一个查询，其中嵌套字段的值用于计算（本例中为price）。以下哪种方法是索引数据的更好方法？

{
      "name": "John",
      "age": 50,
      "country": "US",
      "subscription": {
        "Plan1": {
          "price": 100,
          "date": "June 5th"
        },
        "Plan2": {
          "price": 50,
          "date": "June 6th"
        }
      }
    }

OR

{
  "name": "John",
  "age": 50,
  "country": "US",
  "subscription": [
    {
      "name": "Plan1",
      "price": 100,
      "date": "June 5th"
    },
    {
      "name": "Plan2"
      "price": 50,
      "date": "June 6th"
    }
  ]
}

查询将在“计划名称”和“价格”上进行过滤，并且“价格”将用于分数计算。计划的数量可能超过20个。
编辑1：方法2的示例查询

{
  "query": {
    "function_score": {
      "query": {
        "bool": {
          "filter": [
            {
              "range": {
                "createdatutc": {
                  "gte": "2022-11-01T00:00:00.000Z",
                  "lt": "2023-05-06T00:00:00.000Z",
                  "format": "strict_date_optional_time"
                }
              }
            },
            {
              "terms": {
                "country": [
                  "US"
                ]
              }
            },
            {
              "term": {

                  "value": "Plan1"
                } 
              }
            }
          ]
        }
      },
      "functions": [
        {
          "filter": {
            "query_string": {
              "default_field": "name",
              "query": "\"john\""
            }

              "source": "for (item in params._source.subscription) {if (item.name == 'Plan1') {return item.price}}"
            }
          }
        }
      ],
      "score_mode": "sum",
      "boost_mode": "replace"
    }
  }
}
