The aggregation takes into account a query - but not a post-filter. I'm not sure of the rationale behind the difference.
The java api for traversing results is quite painful - but I think a good part of that is due to Java & the fact that there is very little polymorphic behaviour between aggregation results (some have single results, others have buckets, some have sub-aggregations, some dont). The only alternative that I can think of is a completely type-less navigation of the data - which does little more than navigate the JSON document. Hope that helps a bit.
