Adrian, Thanks for that. I had a feeling that that might be the case.
Any tips on improving aggregation performance. I'm working with a 20 shard index that is loaded on a 20 node cluster. Geohash grid aggregations on the entire data set (with the size set to unlimited - a requirement) can take as long as 8 seconds (and return ~ 1 million buckets). I am very happy with that performance, but if there are any tricks to improve it I would be glad to do so.
