elastic聚合查询没数据

Question

     BoolQueryBuilder boolQuery = QueryBuilders.boolQuery();

        boolQuery.mustNot(QueryBuilders.termQuery("city", "上海"));


        TermsAggregationBuilder builder =  AggregationBuilders.terms("cityagg").field("city").size(10);

        Query build = new NativeSearchQueryBuilder()
                .withQuery(boolQuery) //添加查询条件
                .withAggregations(builder) // 添加聚合条件
                .build();
        System.out.println(JSONObject.toJSONString(build));
        SearchHits<Hotel> ress  = elasticsearchTemplate.search(build, Hotel.class);

        System.out.println(JSONObject.toJSONString(ress.getAggregations()));

打印结果是{}，一个空的括号
