Class GeoHashGridAggregation

A multi-bucket aggregation that works on geo_point fields and groups points into buckets that represent cells in a grid. The resulting grid can be sparse and only contains cells that have matching data. Each cell is labeled using a geohash which is of user-definable precision.

ShardSize

To allow for more accurate counting of the top cells returned in the final result the aggregation defaults to returning max(10,(size x number-of-shards)) buckets from each shard. If this heuristic is undesirable, the number considered from each shard can be over-ridden using this parameter.

Declaration
public int? ShardSize { get; set; }
Property Value
Type Description
int?

Size

The maximum number of geohash buckets to return. Defaults to 10,000. When results are trimmed, buckets are prioritised based on the volumes of documents they contain.

Declaration
public int? Size { get; set; }
Property Value
Type Description
int?
