我们已经将ElasticSearch从5.5升级到6.4，我们有了直方图聚合，我们希望以定义的顺序提供新版本，以提供对此错误的错误并在下面进行查询

                }
            }

    }
}

它在5.5中工作正常，但在6.4中给出了错误 删除订单后，它的工作原理，但我需要它与键排序 room_types_group.check_availability.min_avg_price.value 我如何在6.4中做到这一点 检查这没有帮助 https://www.elastic.co/guide/en/elasticsearch/reference/6.x/search-aggregations-bucket-terms-aggregation.html#search-aggregations-bucket-terms-aggregation-order
