在elasticsearch中用max_score进行字段折叠排序

Question

我有查询后查询

localhost:8000/_search/？pretty=true&q=abbeline+black

{
  "aggs": {
    "dedup": {
      "terms": {
        "field": "image_url_hash",
        "size":0
      },
      "aggs": {
        "dedup_docs": {
          "top_hits": {
            "size": 1
          }
        }
      }
    }
  }
}

我将此html" target="_blank">请求更改为localhost:8000/_search/？pretty=true&q=abbeline+black

{
  "aggs": {
    "dedup": {
      "terms": {
        "field": "image_url_hash",
        "order": {
          "top_hit": "desc"
        }
      },
      "aggs": {
        "dedup_docs": {
          "top_hits": {}
        },
        "top_hit" : {
            "max": {
            "script": "_score"
          }
        }

      }
    }
  }
}

我一直得到这个错误

有人能帮我如何按max_score而不是按doc_counts排序吗？

Answer 1

根据错误dynamic scripting for[groovy]，只需在ElasticSearch.yml配置文件中（在所有节点上）启用动态脚本。

如果您使用的是ES 1.6+，则：

script.inline: on

如果您使用的是早期版本：

script.disable_dynamic: false
