问题描述

我正在尝试在Elasticsearch中执行查询，以从特定日期范围重新使用特定用户.结果应按userId分组并在trackTime字段上排序，我能够通过使用聚合来使用组，但是我无法在tracktime上对聚合存储桶进行排序，因此我写下了以下查询

I am trying to execute a query in elasticsearch to get reuslt of specific users from certain date range. the results should be grouped by userId and sorted on trackTime field, I am able to use group by using aggregation but i am not able to sort aggregation buckets on tracktime, i write down the following query

GET _search
{
"size": 0,
"query": {
    "filtered": {
        "query": {
            "bool": {
                "must": [
                    {
                        "range": {
                            "trackTime": {
                                "from": "2016-02-08T05:51:02.000Z"
                            }
                        }
                    }
                ]
            }
        },
        "filter": {
            "terms": {
                "userId": [
                    9,
                    10,
                    3
                ]
            }
        }
    }
},
"aggs": {
    "by_district": {
        "terms": {
            "field": "userId"
        },
        "aggs": {
            "tops": {
                "top_hits": {
                    "size": 2
                }
            }
        }
    }
}
 }

我还应该使用什么来对热门结果进行排序?预先感谢...

推荐答案

您可以像使用 sort 一样.

"aggs": {
"by_district": {
    "terms": {
        "field": "userId"
    },
    "aggs": {
        "tops": {
            "top_hits": {
                "sort": [
                    {
                        "fieldName": {
                            "order": "desc"
                        }
                    }
                ],
                "size": 2
            }
        }
        }
     }
 }
