记一次es restAPI的filters聚合

pointMap.forEach((provinceName, points) -> {
    GeoPolygonQueryBuilder polygonFilterBuilder = QueryBuilders.geoPolygonQuery("location", points);
    FiltersAggregationBuilder filtersAggregationBuilder = AggregationBuilders.filters(provinceName, polygonFilterBuilder);
    searchSourceBuilder2.aggregation(filtersAggregationBuilder);
});

final Aggregations aggregations = searchResponse.getAggregations();

Iterator<Aggregation> iterator = aggregations.iterator();

 while (iterator.hasNext()) {
            Aggregation aggregation = iterator.next();
            province = aggregation.getName();
            List<? extends Filters.Bucket> buckets = ((ParsedFilters) aggregations.get(province)).getBuckets();
//主要是在从聚合类取值时 要先获取name将其转换成对应的类再获取buckets

           
           
        }
