Mapping a geo point field

ElasticSearch natively supports the use of geolocation types: special types that allow you to localize your document in geographic coordinates (latitude and longitude) around the world.

There are two main document types used in the geographic world: point and shape. In this recipe, we'll see geo point, the base element of geolocation.

Getting ready

You need a working ElasticSearch cluster.

How to do it...

The type of the field must be set to geo_point in order to define a geo point.

You can extend the earlier order example by adding a new field that stores the location of a customer. The following will be the result:

{
  "order": {
    "properties": {
      "id": {
        "type": "string",
        "store": "yes",
        "index": "not_analyzed"
      },
      "date": {
        "type": "date",
        "store": "no",
        "index": "not_analyzed"
      },
      "customer_id": {
        "type": "string",
        "store": "yes",
        "index": "not_analyzed"
      }...
