|
AggregationBuilder aggregation =
|
|
AggregationBuilders
|
|
.significantTerms("significant_countries")

|
|
|
// Let say you search for men only
|
|
SearchResponse sr = client.prepareSearch()
|
|
.setQuery(QueryBuilders.termQuery("gender", "male"))
|
|
.addAggregation(aggregation)
|
|
.get();
|
|
--------------------------------------------------

|
|
|
|
// For each entry
|
|
for (SignificantTerms.Bucket entry : agg.getBuckets()) {
|
|
entry.getKey(); // Term
|
|
entry.getDocCount(); // Doc count
|

}
