字段脚本中 _score 的特定值

Question

我只需要从 ES 中的 _score 获取一些字段。

例如这样：创建我自己的json-object并返回它，或者只返回特定的值（但我真的不明白怎么做）

{
    "script_fields": {
        "total_goals": {
            "script": {
                "lang": "painless",
                "inline": "if ((params._source.f_data & 3) == 0) {return params.tee;} else {return false;}",
        "params": {
            "tee": {
                "f_data": params._source.f_data,
                "s_data": params._source.s_data,
                "text": params._source.text,
            }
        }
    }
}

文档：

$ curl -XGET "$ES_URL/please/_search?pretty"
{
  "took" : 0,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 1,
      "relation" : "eq"
    },
    "max_score" : 1.0,
    "hits" : [
      {
        "_index" : "please",
        "_type" : "_doc",
        "_id" : "pleaseworkforme14",
        "_score" : 1.0,
        "_source" : {
          "_class" : "com.example.test.ind.info.ElasticData",
          "f_data" : "123",
          "s_data" : "Everyone4",
          "text" : "Blue\n"
        }
      }
    ]
  }
}

PS：脚本中的括号可能放置不正确
