field - 如果在 elasticsearch 查询中使用 script_fields，则不再有 _source

Question

我正在运行一个像这样的简单查询:

{
  "query": {
    "term": {
      "statuses": "active"
    }
  },
  "script_fields": {
    "test": {
      "script": "_source.name"
    }
  }
}

问题是，一旦我引入了 script_fields，我的结果中就不再有 _source。

我试过:

{
  "fields": [
    "_all"
  ],
  "query": {
    "term": {
      "statuses": "active"
    }
  },
  "script_fields": {
    "email": {
      "script": "_source.name"
    }
  }
}

和

{
  "fields": [
    "*"
  ],
  "query": {
    "term": {
      "statuses": "active"
    }
  },
  "script_fields": {
    "email": {
      "script": "_source.name"
    }
  }
}

但他们没有任何区别。除了 script_fields 之外，还有没有办法让 _source 返回？

Answer 1

在fields数组中，让它加载_source:

{
  "stored_fields": [
    "_source"
  ],
  "query": {
    "term": {
      "statuses": "active"
    }
  },
  "script_fields": {
    "email": {
      "script": "_source.name"
    }
  }
}
