通过术语弹性​​搜索限制过滤器

Question

我会为每个术语设置一个大小限制，3个检索术语“标记”的结果，5个结果用于术语“档案”，1个结果用于术语“个性”。

我可以使用限制过滤器或其他解决方案吗？

{
    "_source":{
      "include":[
        "path",
        "type"
      ]
    },
    "query":{
      "bool":{
        "should":[
          {
            "match":{
              "title.acp":{
                "query":"car",
                "boost":10
              }
            }
          },
          {
            "match":{
              "title.acp":{
                "query":"car",
                "fuzziness":"AUTO",
                "prefix_length":3
              }
            }
          }
        ],
        "filter":[
          {
            "terms":{
              "type":[
                "tag",
                "dossier",
                "personality"
              ]
            }
          }
        ]
      }
    },
    "highlight":{
      "fields":{
        "title.acp":{}
      }
    }
  };

看起来像一个给定的标题＆＃39;您希望每个类型的前x个文档都是＆＃39; x＆＃39;因type

而异

执行此操作的一种方法是使用聚合filter和top-hits：

示例：

{
   "size": 0,
   "query": {
      "bool": {
         "should": [
            {
               "match": {
                  "title.acp": {
                     "query": "car",
                     "boost": 10
                  }
               }
            },
            {
               "match": {
                  "title.acp": {
                     "query": "car",
                     "fuzziness": "AUTO",
                     "prefix_length": 3
                  }
               }
            }
         ],
         "filter": [
            {
