java - Elasticsearch查询聚合spring框架elasticsearsh如何？

Question

我想使用以下方式聚合查询结果:

  "aggs": {
"agg1": {
      "terms": {
        "field": "basket_id_1",
        "size":0
      },
      "aggs": {
        "basket_id_2": {
          "terms": {
            "field": "basket_id_2",
            "size":0
          },
          "aggs": {
            "basket_id_3": {
              "terms": {
                "field": "basket_id_3",
                "size":0
              }
            }
          }
        }
      }
    }
  }

我如何使用elasticsearch spring框架在java中做到这一点？我该调用哪个方法？在哪个物体上？

这是我到目前为止的 java 代码:

       NativeSearchQueryBuilder searchQueryNative = new NativeSearchQueryBuilder()
            .withIndices(this.getIndex()).withTypes(this.getType());

    searchQueryNative.
    SearchQuery searchQuery = searchQueryNative.build();

    Page<Object> result = this.getElasticsearchTemplate().queryForPage(
            searchQuery, Object.class).;

当您与以下人员一起工作时:

@Bean
public Client client() {
    return nodeBuilder().settings(buildNodeSettings()).node().client();
}

你可以利用:

client().prepareSearch()
    .setQuery( /* your query */ )
    .addAggregation( /* add an aggregation */ )
    .execute().actionGet();
