Executing the geo distance aggregation


Among the other standard types that we have seen in previous aggregations, ElasticSearch allows executing aggregations against a geo point: geo distance aggregations. This is an evolution of the previously discussed range aggregations built to work on geo locations.

Getting ready

You need a working ElasticSearch cluster and an index populated with the script (executing_geo_distance_aggregations.sh) available at https://github.com/aparo/elasticsearch-cookbook-second-edition.

How to do it...

Using the position field available in documents, we will aggregate the other documents in four ranges:

  • Fewer than 10 kilometers

  • From 10 to 20 kilometers

  • From 20 to 50 kilometers

  • From 50 to 100 kilometers

  • Above 100 kilometers

To execute geo distance aggregations, we will perform the steps given as follows:

  1. To achieve these goals, we will create a geo distance aggregation with a code similar to this one:
