java代码中 操作es api遇到问题
TermsAggregationBuilder brandAgg = AggregationBuilders.terms("brand_agg");
brandAgg.field("brandId").size(50);
brandAgg.subAggregation(AggregationBuilders.terms("brand_name_agg")).field("brandName").size(1);
brandAgg.subAggregation(AggregationBuilders.terms("brand_img_agg")).field("brandImg").size(1);
sourceBuilder.aggregation(brandAgg);
TermsAggregationBuilder brandAgg = AggregationBuilders.terms("brand_agg").field("brandId").size(50)
.subAggregation(AggregationBuilders.terms("brand_name_agg").field("brandName").size(50))
.subAggregation(AggregationBuilders.terms("brand_img_agg").field("brandImg").size(50));
sourceBuilder.aggregation(brandAgg);
上面的代码和下面的有什么不一样吗 为什么使用上面的就会报错
