Geo Distance Aggregation Usage

Fluent DSL example

a => 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

edit

new 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 }
    }
}

Example json output.

{
  "rings_around_amsterdam": {
    "geo_distance": {
      "field": "locationPoint",
      "origin": {
        "lat": 52.376,
        "lon": 4.894
      },
      "ranges": [
        {
          "to": 100.0
        },
        {
          "from": 100.0,
          "to": 300.0
        },
        {
          "from": 300.0
        }
      ]
    }
  }
}

Handling Responses

edit

response.ShouldBeValid();
var ringsAroundAmsterdam = response.Aggregations.GeoDistance("rings_around_amsterdam");
ringsAroundAmsterdam.Should().NotBeNull();
ringsAroundAmsterdam.Buckets.FirstOrDefault(r => r.Key == "*-100.0").Should().NotBeNull();
ringsAroundAmsterdam.Buckets.FirstOrDefault(r => r.Key == "100.0-300.0").Should().NotBeNull();
ringsAroundAmsterdam.Buckets.FirstOrDefault(r => r.Key == "300.0-*").Should().NotBeNull();
