Elasticsearch提供完整的Java API来使用聚合。 请参阅[聚合指南](https://www.elastic.co/guide/en/elasticsearch/reference/5.6/search-aggregations.html)。

使用 `AggregationBuilders` 构建对象,增加到搜索请求中:
10+
11+
```
12+
import org.elasticsearch.search.aggregations.AggregationBuilders;
13+
14+
```
15+
16+
```
17+
SearchResponse sr = node.client().prepareSearch()
18+
.setQuery( /* your query */ )
19+
.addAggregation( /* add an aggregation */ )
20+
.execute().actionGet();
21+
```
