我使用script_score自定义得分:

GET /customer/_search
{
    "query": {
        "function_score": {
            "query": {
                "match": {
                    "name": "Mark"
                }
            },
            "script_score": {
              "script": {
                "lang": "painless",
                "file": "test"
              }
            }
        }
    }
}

我设置了"file": "test",并将test.groovy文件放在config/scripts目录中,但是出现了以下错误:

{
  "error": {
    "root_cause": [
      {
        "type": "illegal_argument_exception",
        "reason": "[script] unknown field [file], parser not found"
      }
    ],
    "type": "illegal_argument_exception",
    "reason": "[script] unknown field [file], parser not found"
  },
  "status": 400
}

[script] unknown field [file], parser not found!为什么?我需要安装一些插件吗?

File scripts have been removed在ES 6.0中,您现在应该改为使用stored scripts

您可以轻松migrate your Groovy script to Painless

首先,存储您的脚本:

POST _scripts/test
{
  "script": {
    "lang": "painless",
    "source": "Math.log(_score * 2)"
  }
}

然后在查询中使用它:

GET /customer/_search
{
    "query": {
        "function_score": {
            "query": {
                "match": {
                    "name": "Mark"
                }
            },
            "script_score": {
              "script": {
                "id": "test"
              }
            }
        }
    }
}
