@StableMinor(version="17.0",
             sinceVersion="9.0")
public class GeoDistanceAggregation
extends AbstractSubAggregationAwareAggregation
implements IFieldAwareAggregation

Aggregation that aggregates the documents based on a center point and a collection of ranges.
This aggregation produces a result of type IGeoDistanceAggregationResult. Each range will generate a bucket to store documents that that have a distance that fit into the given range.

The given field will be used to calculate the geo distance to the given center point. Thus, the given field must be of the data type DocumentTypeField.DataType.GEO_POINT.

If the given field is a list, the closest point to the center will be considered.

It is important to notice that at least one range must be added.
