使用significant_terms查询参加活动和jack类似的参与者

现有索引event，映射信息如下

{

  "event" : {

    "mappings" : {

      "properties" : {

        "attendees" : {

          "type" : "keyword"

        },

        "name" : {

          "type" : "text"

        }

      }

    }

  }

}

其中attendees表示活动参与者
数据如下

PUT event/_doc/1

{

  "name":"草莓音乐节",

  "attendees":["rose","jack"]

}



PUT event/_doc/2

{

  "name":"歌剧",

  "attendees":["lucy","rose"]

}



PUT event/_doc/3

{

  "name":"周杰伦演唱会",

  "attendees":["lucy","jack"]

}



PUT event/_doc/4

{

  "name":"芭蕾舞",

  "attendees":["jack","rose"]

}

通过以下方法

GET event/_search

{

  "query": {

    "term": {

      "attendees": "jack"

    }

  },

  "aggs": {

    "significant_attendees": {

      "significant_terms": {

        "field": "attendees"

      }

    }

  }

}

结果是
 

我想让结果返回类似
