在 elasticsearch 中使用聚合时出错

问题描述

我正在使用 elasticsearch java Api 并且我正在尝试运行此查询来检索结果。但我正在解析异常。 你能帮我找出问题出在哪里吗？ 我会很感激

{
    "size": 0,"query": {
        "bool": {
            "must": [{
                    "query_string": {

                }
            ],"adjust_pure_negative": true,"boost": 1.0
        }
    },"aggregations": {

                    },{
                        "_key": "asc"
                    }
                ]
            },"aggregations": {
                "groupBySf": {
                    "terms": {

                                "_count": "desc"
                            },{
                                "_key": "asc"
                            }
                        ]
                    }
                }
            }
        }
    }
}

这是我得到的例外

解决方法

execution_hint 参数不接受 global_ordinals_low_cardinality 值，而只接受 map 和 global_ordinals。

您需要确保客户端 Java API 的版本与 ES 集群的版本同步，因为您似乎使用的是旧客户端 Java API。
