Elasticsearch-3个嵌套级别聚合过滤器不起作用

Question

我具有以下要求：

拉特说我的aggregation在场上-branchOfficeLocations.regTypeDRPCounts.drpType而我的filter在场上-branchOfficeLocations.branchAddress.countryCode

我需要将过滤器放在聚合部分的某处，但似乎无法获得正确的查询。该过滤器位于第二级字段上，与第二级上的聚合字段不同。

任何帮助将不胜感激！

下面是我的查询：

    "from": 0,
    "size": 0,
    "query": {
        "bool": {
            "must": [
