Spring数据ElasticSearch 3.2

final SearchQuery searchQuery =
        new NativeSearchQueryBuilder()
            .withQuery(QueryHelper.boolQueryBuilder(id))
            .addAggregation(
                terms("sequence")
                    .field("sequence.keyword")
                    .subAggregations(subAggregations()))
            .addAggregation(sumBucket("sum_bucket", "sequence>amount"))
            .build();

现在，由于NativeSearchQueryBuilder的addAggregation方法接受AbstractAggregationBuilder，并且sumBucket的类型为PipelineAggregationBuilder，因此无法将此值传递给addAggregation（sumBucket（“sum\u bucket”，“sequence

Answer 1

我刚刚检查了Spring数据Elasticsearch和Elasticsearch本身的代码。对于Spring Data Elasticsearch，当前无法使用PipelineAggregationBuilder派生聚合。

我不知道为什么Elasticsearch有两种不同的聚合类层次结构，但Spring Data Elasticsearch目前只能处理AggregationBuilder而不能处理PipelineAggregationBuilder派生类。

为此，我在Jira创建了一个问题。
