I have an elastic query as



{

  "size": 0,

  "aggs": {

    "group_by_cluster": {

      "terms": {

        "field": "cluster"

      }

    }

  }

}


http://localhost:9200/index/type/_search



I am getting the result when tried with postman. Now trying to write corresponding java code. (ElasticSearch version 5.5)



SearchQuery searchQuery = new NativeSearchQueryBuilder()

.withIndices("index")

.withTypes("type")

.addAggregation(AggregationBuilders

.global("agg")          

.subAggregation(AggregationBuilders.terms("group_by_cluster").field("cluster")))

.build();

 Aggregations aggregations = elasticTemplate.query(searchQuery, new 

 ResultsExtractor<Aggregations>() {

 @Override

 public Aggregations extract(SearchResponse response) {

 return response.getAggregations();

 }

 } );


But the result is empty. Please help me on this

A simple yellow flag (also called the "Yellow Jack") had historically been used to signal quarantine (it stands for Q among signal flags), but now indicates the opposite, as a signal of a ship free of disease that requests boarding and inspection.
