Elasticsearch筛选具有相同字段值的文档ID计数

后过滤器:

在计算了聚合之后,post_过滤器将应用于搜索请求末尾的搜索结果

不能根据查询或后筛选中字段的出现次数筛选文档,也不能使用聚合结果筛选查询中的文档。

一。获取给定次数出现的术语并在文档中搜索这些术语(2次调用弹性搜索)

2。使用 top_hits

映射:

{
  "index48" : {
    "mappings" : {
      "properties" : {
        "name" : {
          "type" : "text",
          "fields" : {
            "keyword" : {
              "type" : "keyword",
              "ignore_above" : 256
            }
          }
        }
      }
    }
  }
}

查询:

  "size": 0,
  "aggs": {
    "NAME": {
      "terms": {
        "field": "name.keyword",
        "size": 10
      },
      "aggs": {
        "documents": {

          },
          "script": "if(params.path>=1 && params.path<=3) return true"
        }
      }
      }
    }
  }
