SumBuilder field2Sum = AggregationBuilders.sum(sum_field2).field(field2);
SumBuilder field3Sum = AggregationBuilders.sum(sum_field3).field(field3);
field1Terms.subAggregation(field2Sum ).subAggregation(field3Sum );
...
srb.addAggregation(pIdTerms);
...
SearchResponse sr = srb.execute().actionGet();
