弹性搜索方面到聚合

Question

需要帮助将此查询从使用facet_filter转换为在ES 2.0中使用aggs，因为ES 2.0及更高版本不再支持facet。

{
  "facets": {
    "format": {
      "terms": {
        "field": "documentary_tag_id",
        "size": 10,
        "exclude": ["2"]
      },
      "facet_filter": {
        "term": {
          "documentary_tag_id": ["2"]
        }
      }
    }
  },
  "sort": [
    "_score",
    {
      "documentary_tag_name": {
        "order": "desc"
      }
    }
  ]
}

聚合几乎与你应该使用smth一样

GET _search
{
  "aggs": {
    "format_filter": {
      "filter": {
        "terms": {
          "documentary_tag_id": [
            "2"
          ]
        }
      },
      "aggs": {
        "format": {
          "terms": {
            "field": "documentary_tag_id",
          "exclude" : "2"
          }
        }
      }
    }
  }
}

但如果你are filtering有一点不同的想法，要读取你需要获得的值 format_filter ，那么你会发现聚合。聚合内部的Filtering是相同的
