Geo Distance Aggregation Usage
editGeo Distance Aggregation Usage
editFluent DSL example
edita => a
.GeoDistance("rings_around_amsterdam", g => g
.Field(p => p.LocationPoint)
.Origin(52.376, 4.894)
.Ranges(
r => r.To(100),
r => r.From(100).To(300),
r => r.From(300)
)
)
Object Initializer syntax example
editnew GeoDistanceAggregation("rings_around_amsterdam")
{
Field = Field((Project p) => p.LocationPoint),
Origin = "52.376, 4.894",
Ranges = new List<AggregationRange>
{
new AggregationRange { To = 100 },
new AggregationRange { From = 100, To = 300 },
new AggregationRange { From = 300 }
}
}
