I am using Elasticsearch 7.11.1 and going to use top\_metric aggregation to get the top records under the terms aggregation bucket. And my query is something like the following:

> {  
> "size": 0,  
> "query": {  
> "bool": {  
> "must": [  
> {  
> "terms": {  
> "type": [  
> "data\_type"  
> ]  
> }  
> }  
> ]  
> }  
> },  
> "aggregations": {  
> "field1": {  
> "terms": {  
> "field": "field1",  
> "size": 10  
> },  
> "aggregations": {  
> "field2": {  
> "terms": {  
> "field": "field2",  
> "size": 10  
> },  
> "aggregations": {  
> "field3": {  
> "terms": {  
> "field": "field3",  
> "size": 10  
> },  
> "aggregations": {  
> "amount": {  
> "extended\_stats": {  
> "field": "amount"  
> }  
> },  
> "hits\_here": {  
> "top\_metrics": {  
> "metrics": [  
> {  
> "field": "field3"  
> },  
> {  
> "field": "field4"  
> },  
> {  
> "field": "field5"  
> }  
> ],  
> "sort": "\_score"  
> }  
> }  
> }  
> }  
> }  
> }  
> }  
> }  
> },  
> "track\_total\_hits": 2147483647  
> }

This query yields the expected results from ES, and now I would like to use this via JAVA API but I'm unable to find its related JAVA class in both ES 7.11 and 7.14, am I missing anything here or is it actually not available in API? If not available in API, is there any options to use the similar functionality?

Have you seen the [TopMetricAggregationBuilder](https://github.com/elastic/elasticsearch/blob/7.11/client/rest-high-level/src/main/java/org/elasticsearch/client/analytics/TopMetricsAggregationBuilder.java)?

Thank you for pointing this out. It worked.

Is there a chance that Top Metric Aggregation support will be added to Java Transport Client API?

Not sure I understand the question. The transport client is not intended for client-to-cluster communication, so this is only available in the REST client.
