如何从Filter Aggregation返回的文档集中将当前聚合上下文缩小到特定范围？

尝试以下聚合：

{  "aggs": {    "continents": {      "nested": {        "path": "continents"      },      "aggs": {        "asia_continent": {          "filter": { "query": {   "match": {     "continents.name": "asia"   } }          },          "aggs": { "countries": {   "nested": {     "path": "continents.countries"   },   "aggs": {     "india_country": {       "filter": {         "query": {"match": {  "continents.countries.name": "india"}         }       },       "aggs": {         "states": {"nested": {  "path": "continents.countries.states"},"aggs": {  "count": {    "value_count": {      "field": "continents.countries.states.wins"    }  }}         }       }     }   } }          }        }      }    }  }}
