Elastic Stack Elasticsearch

Hi, I want to translate this curl into working java code in spring -
curl -XGET 'localhost:9200/catalog/_search?pretty' -H 'Content-Type: application/json' -d' { "size": 0,
"aggs": { "types": {
"terms": {
"field": "types.keyword"
},
"aggs": {
"subtypes": {
"terms": {
"field": "subtypes.keyword"
}
Here I am using sub aggregation.

If you are using Java High Level Client, try:

  var aags = AggregationBuilders.terms("types").field("types.keyword")
        .subAggregation(AggregationBuilders.terms("subtypes"))
        .field("subtypes.keyword");
    var searchRequest = new SearchRequest("index");
    var sourceBuilder = new SearchSourceBuilder();
    sourceBuilder.size(0);
    sourceBuilder.aggregation(aags);
    searchRequest.source(sourceBuilder);
    var response = esClient.search(searchRequest, RequestOptions.DEFAULT);
