我正在尝试从一个价格最低的文档中获取所有字段。使用min我只能得到特定的价格。我应该如何检索一个文档的所有字段。
我已经编写了这段代码来检索最低价格
AggregationBuilder aggregation = AggregationBuilders.nested("nestedAgg").path("carSpecPojo")
.subAggregation(AggregationBuilders.min("carSpecAgg").field("carSpecPojo.price"));
SearchQuery searchQuery = (SearchQuery) new NativeSearchQueryBuilder()
.addAggregation(aggregation).build();
Aggregations aggregations = elasticsearchTemplate.query(searchQuery, new ResultsExtractor<Aggregations>() {
@Override
public Aggregations extract(SearchResponse response) {
return response.getAggregations();
}});
Nested nest = aggregations.get("nestedAgg");
Min min = nest.getAggregations().get("carSpecAgg");
我的弹性文件将是这样的
"brand_name": "maruti",
"model": "i20",
"year": "2015",
"carSpecPojo": {
"engine_power": "400hp",
"price": 9000000,
"transmission_type": "auto",
"airbag": "yes",
"abs": 1,
"max_speed": "170kmp",
"color": "black",
"fuel": "petrol",
"mileage": 5,
"door": 4,
"seat_capacity": 4
}
}
当我得到最低价格XXXXXXX时,我需要本文档中的所有字段
