java写一个es的聚合查询,功能为匹配索引一下面的字段一和字段二,搜索的结果按字段三的值不同来分组计算命中数量
时间: 2023-03-07 07:14:04 浏览: 112
可以使用下面的代码:
```java
SearchResponse response = client.prepareSearch("index_name")
.setQuery(QueryBuilders.matchQuery("field_one", "value_one"))
.setQuery(QueryBuilders.matchQuery("field_two", "value_two"))
.addAggregation(
AggregationBuilders.terms("group_by_field_three").field("field_three")
)
.execute()
.actionGet();
```

java写一个es的聚合查询,功能为匹配索引一下面的字段一、字段二,结果按字段三的值不同来计算命中数量
你可以使用以下Java代码来编写ES聚合查询:SearchRequest searchRequest = new SearchRequest(index);
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder(); // 聚合查询
AggregationBuilder aggregationBuilder = AggregationBuilders.terms("agg_name")
.field("field_three")
.subAggregation(AggregationBuilders.filter("filed_one_two_filter")
.filter(QueryBuilders.boolQuery()
.must(QueryBuilders.termQuery("field_one", "value_one"))
.must(QueryBuilders.termQuery("field_two", "value_two"))
)
);searchSourceBuilder.aggregation(aggregationBuilder);
searchRequest.source(searchSourceBuilder); SearchResponse searchResponse = client.search(searchRequest);
java实现es多字段聚合查询
Java实现ES多字段聚合查询,可以使用Elasticsearch官方提供的Java API进行操作。以下是一个简单的示例代码:
```java
import org.elasticsearch.action.search.SearchResponse;
import org.elasticsearch.client.transport.TransportClient;
import org.elasticsearch.common.transport.InetSocketTransportAddress;
import org.elasticsearch.index.query.QueryBuilders;
import org.elasticsearch.search.aggregations.AggregationBuilders;
import org.elasticsearch.search.aggregations.bucket.terms.Terms;
import org.elasticsearch.transport.client.PreBuiltTransportClient;
import java.net.InetAddress;
import java.net.UnknownHostException;
public class MultiFieldAggregationExample {
public static void main(String[] args) throws UnknownHostException {
TransportClient client = new PreBuiltTransportClient(
org.elasticsearch.common.settings.Settings.EMPTY)
.addTransportAddress(new InetSocketTransportAddress(
InetAddress.getByName("localhost"), 9300));
SearchResponse response = client.prepareSearch("index-name")
.setQuery(QueryBuilders.matchAllQuery())
.addAggregation(
AggregationBuilders.terms("agg")
.field("field1")
.field("field2")
)
.get();
Terms agg = response.getAggregations().get("agg");
for (Terms.Bucket entry : agg.getBuckets()) {
System.out.println(entry.getKey() + " : " + entry.getDocCount());
}
client.close();
}
}
```
在上面的示例中,我们使用了TransportClient连接到本地的ES服务器,并对索引为“index-name”的所有文档进行了查询。然后,我们使用AggregationBuilders构建了一个多字段聚合查询,其中包括了两个字段:field1和field2。最后,我们从响应中获取了聚合结果,并输出了每个桶的键和文档计数。
需要注意的是,上面的代码仅仅是一个示例,实际使用中还需要根据具体的需求进行调整和优化。
