Hello,
I'm using ElasticSearch 2.4.3 and was wondering if there is any way to use geohash_grid as a sub-aggregation.
A bit of context : I store lat/lon coordinates alongside a user ID and a timestamp, so there may be multiple coordinates for a single user ID. I would like to do a geohash_grid aggregation, but only on the last coordinates of every user ID.
Is this possible with the version of ES I'm using ?
