Hi @Anna_Mikhilev

I did this example, maybe help you.

```auto
    Map<String, Aggregation> map = new HashMap<>();

    Aggregation subAggregation = new Aggregation.Builder()
        .avg(new AverageAggregation.Builder().field("revenue").build())
        .build();

    Aggregation aggregation = new Aggregation.Builder()
        .terms(new TermsAggregation.Builder().field("director.keyword").build())
        .aggregations(new HashMap<>() {{
          put("avg_renevue", subAggregation);
        }}).build();

    map.put("agg_director", aggregation);

```
