弹性搜索 java stats_buckets

如何解决弹性搜索 java stats_buckets

我使用聚合和 stats_buckets 在 json 中提出了一个 elasticsearch 请求。

我想检索每个电话号码的通话次数。

我在 java 中找不到 stats_buckets 的语法。

我使用 Elasticsearch 7.4.1

怎么办？谢谢

                        }
                    }
                }
            ]
        }
    },"aggs": {
        "caller_number": {
            "terms": {
                "field": "caller_number.keyword"
            }
        },"total_sum": {
            "stats_bucket": {
                "buckets_path": "caller_number._count" 
            }
        }
    },"size": 0
}'

Java：

    StatsBucketPipelineAggregationBuilder bs = PipelineAggregatorBuilders.statsBucket("total_sum","terms_caller_number._count");

this.elastic
    .prepareSearch("doc")
    .setQuery(query)
    .addAggregation(AggregationBuilders
            .terms("terms_caller_number")
            .field("caller_number.keyword")
            .subAggregation(AggregationBuilders
            .subAggregation(bs)
    )
    .execute()
    .actionGet();
