```auto { "aggs": { "my-agg-name": { "terms": { "field": "my-field" }, "aggs": { "my-sub-agg-name": { "avg": { "field": "my-other-field" } } } } } } ``` I wanted to perform the above Elasticsearch query in java using the new Elasticsearch java api client . I am using Elasticsearch version 7.16 . Can someone please help me in building the same query using the new Elasticsearch java api client . ---

That should be: ```java SearchRequest search = SearchRequest.of(b1 -> b1 .aggregations("my-agg-name", b2 -> b2 .terms(b3 -> b3 .field("my-field") ) .aggregations("my-sub-agg-name", b3 -> b3 .avg(b4 -> b4 .field("my-other-field") ) ) ) ); ``` ---

Hi @swallez , This looks perfect . Just one more doubt the _of_ function is available for 7.16 and not for 7.15 version . If possible can you please share a solution which can be used for 7.15 as well . Thanks in Advance . ---

The `SomeClass.of` method is a shortcut for `new SomeClass.Builder()` at the begining and `.build()` at the end: ```auto SearchRequest search = new SearchRequest.Builder() .aggregations("my-agg-name", b2 -> b2 .terms(b3 -> b3 .field("my-field") ) .aggregations("my-sub-agg-name", b3 -> b3 .avg(b4 -> b4 .field("my-other-field") ) ) ) .build(); ``` ---

Thank you so much for clarification @swallez . ---

Hi @swallez , With the above solution i could see query getting created correctly but i am getting below error in runtime . ```auto co.elastic.clients.base.ApiException: null at co.elastic.clients.base.rest_client.RestClientTransport.getHighLevelResponse(RestClientTransport.java:224) at co.elastic.clients.base.rest_client.RestClientTransport.performRequest(RestClientTransport.java:104) at co.elastic.clients.elasticsearch.ElasticsearchClient.search(ElasticsearchClient.java:1283) ``` ---

What version are you using? The stacktrace seems to indicate version 7.15. Version 7.15 was a beta version which is not supported. Please upgrade to version 7.16.2 ---

Yes the issue got resolved while using 7.16.2 . Mapping aggregations from search response also seems to changed. Can you please help me with mapping aggregation values from search response as well ? ---

The API to create an aggregation may not be straightfoward, but for results just follow the API and the completion provided by your IDE. ---
