在Elasticsearch中限制分组结果

这样的事情应该做到：

GET /some_index/some_type/_search?search_type=count{  "aggs": {    "district_1_or_2": {      "filter": {        "bool": {          "should": [ {   "term": {     "district": 1   } }, {   "term": {     "district": 2   } }          ]        }      },      "aggs": {        "district": {          "terms": { "field": "district", "size": 10          },          "aggs": { "top": {   "top_hits": {     "size": 2   } }          }        }      }    }  }}
