Hi!

I'm trying to make a clustering of geo-points and got stuck with a two  
problems.

1. If bucket contains only one document, is there any way to get it's id?
2. Is there any way to get only aggregated data from ES with out of a  
'hits' information? It is really a lot of unnecessary data there.

ES version: 1.1.1

Query example:

> ```
> {
> "size": 1000,
> "aggregations": {
> 'cells': {
> 'geohash_grid': {
> 'field': 'point',
> 'precision': precision,
> },
> 'aggregations': {
> 'lat': {
> 'avg': {
> 'script': '''doc['point'].lat''',
> }
> },
> 'lon': {
> 'avg': {
> 'script': '''doc['point'].lon''',
> }
> }
> }
> }
> },
> 'query': {
> 'constant_score': {
> 'filter': {
> 'exists': {
> 'field': 'point',
> }
> }
> }
> }
> }
> 
> ```

1. The upcoming top\_hits aggregation "may" help here:

[http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-aggregations-bucket-top-hits-aggregation.html](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-aggregations-bucket-top-hits-aggregation.html)

1. If you do localhost:9200/\_search?search\_type=count, the hits will not be  
returned in the most efficient manner possible.
