Create Index with GeoPoint type

Elastic Stack Elasticsearch
4

You'll need to delete the existing index if there is one and create again

public class Message
{
    public GeoLocation Location { get; set; }
}

var defaultIndex = "messages";
var client = new ElasticClient();

if (client.IndexExists(defaultIndex).Exists)
{		
    client.DeleteIndex(defaultIndex);
}
	
client.CreateIndex(defaultIndex, c=> c
    .Mappings(m => m
        .Map<Message>(mm => mm
            .AutoMap()
        )
    )
);

yields

PUT http://localhost:9200/messages
{
  "mappings": {
    "message": {
      "properties": {
        "location": {
          "type": "geo_point"
        }
      }
    }
  }
}
