Easy example of indexing geo-based domain objects to ElasticSearch via #nest

namespace elasticsearch_nest_geoindex_demo
{

  public class Location
  {
    public string Name { get; set; }
    public Coordinate CoordinateObject { get; set; }
    public Coordinate CoordinateString { get; set; }
  }

  public class Coordinate
  {
    public double Lat { get; set; }
    public double Lon { get; set; }
  }

  internal class Program
  {
    private static void Main(string[] args)
    {
      var client = new ElasticClient(new ConnectionSettings(new Uri("http://localhost:9200"))
        .SetDefaultIndex("geopoint-tests")
        .SetTimeout(30 * 1000));

      var rootNodeInfo = client.RootNodeInfo();
      if (!rootNodeInfo.ConnectionStatus.Success)
        throw new ApplicationException("Could not connect to ElasticSearch!",
          rootNodeInfo.ConnectionStatus.OriginalException);

      if (client.IndexExists(i => i.Index("geopoint-tests")).Exists)
        client.DeleteIndex(i => i.Index("geopoint-tests")); //scrub the index

      client.CreateIndex("geopoint-tests", s => s
        .AddMapping<Location>(f => f
          .MapFromAttributes()
          .Properties(p => p
            .GeoPoint(g => g.Name(n => n.CoordinateObject).IndexLatLon())
            .GeoPoint(g => g.Name(n => n.CoordinateString).IndexLatLon())
          )
        )
        );

      //index a few points
      client.IndexMany(new[]
      {
        createLocation("Amsterdam", 52.3740300, 4.8896900),
        createLocation("Rotterdam", 51.9225000, 4.4791700),
        createLocation("Utrecht", 52.0908300, 5.1222200),
        createLocation("Den Haag", 52.0908300, 5.1222200)
      });

      //find locations within 10km of schiphol airport
      var results = client.Search<Location>(s => s
        .Filter(f => f
          .GeoDistance(
            n => n.CoordinateObject,
            d => d.Distance(20.0, GeoUnit.km).Location(52.310551, 4.76974)
          )
        )
      );

      foreach (var doc in results.Documents)
        Console.WriteLine("Found: " + doc.Name);
      Console.WriteLine("Done.");
      Console.ReadLine();
    }

    private static Location createLocation(string name, double latitude, double longitude)
    {
      return new Location
      {
        Name = name,
        CoordinateObject = new Coordinate { Lat = latitude, Lon = longitude },
        CoordinateString =
          string.Format("{0},{1}", latitude.ToString(CultureInfo.InvariantCulture),
            longitude.ToString(CultureInfo.InvariantCulture))
      };
    }
  }
}

In this codes:

client.CreateIndex("geopoint-tests", s => s
.AddMapping(f => f
.MapFromAttributes()
.Properties(p => p
.GeoPoint(g => g.Name(n => n.CoordinateObject).IndexLatLon())
.GeoPoint(g => g.Name(n => n.CoordinateString).IndexLatLon())
)
)
);

Can i replace it so that just mapping geopoint without create index, sir?
