我希望将cost.cost：3.6作为聚合结果，但我得到结果为5 如何在数组中过滤数据？

 RangeQueryBuilder startDateRQB = QueryBuilders.rangeQuery("costs.startDate").gte("2017-02-14T00:00:00+00:00");
        RangeQueryBuilder endDateRQB = QueryBuilders.rangeQuery("costs.endDate").lte("2017-02-15T00:00:00+00:00");
        RegexpQueryBuilder deviceNameREQB= QueryBuilders.regexpQuery("region", "useast.*");
        BoolQueryBuilder bQB=QueryBuilders.boolQuery().must(deviceNameREQB).must(startDateRQB).must(endDateRQB);
        BoolQueryBuilder sQB=QueryBuilders.boolQuery().must(startDateRQB).must(endDateRQB);
        SearchResponse response = client.prepareSearch(index).setQuery(bQB).addAggregation(AggregationBuilders.sum("Totalcost").field("costs.cost")).execute().actionGet();
        Sum sum=response.getAggregations().get("Totalcost");
        double cost=sum.getValue();
        System.out.println(cost);

我建议你将render定义为嵌套对象。然后，您将能够在内部数据中添加条件（嵌套文档）。

这种方法可以为您的查询提供广泛的可能性。

查看以下解决方案：

costs

让我解释一下每个聚合（按名称）：

costs_agg：嵌套聚合以深入了解成本范围
bool_agg：在嵌套对象上聚合的东西，聚合上方的查询不会被嵌套对象过滤。这里的解决方案是在聚合本身内过滤所需的嵌套文档
cost_sum_agg：最终总和

希望它有所帮助。

根据使用java的elasticsearch数组中的条件获取特定值
