    .subAggregation(AggregationBuilders.terms("genders").field("gender"));
--------------------------------------------------

import org.elasticsearch.search.aggregations.bucket.global.Global;
--------------------------------------------------

[source,java]

// sr is here your SearchResponse object
Global agg = sr.getAggregations().get("agg");
agg.getDocCount(); // Doc count
