Using geo distance filter

When you are working with geolocations, one of the most common tasks is to filter results based on their distance from a location. This scenario covers the following common site requirements:

  • Finding the nearest restaurant in a 20 km distance
  • Finding your nearest friends in a 10 km range

The geo_distance filter is used to achieve this goal.

Getting ready

You need a working ElasticSearch cluster and an index populated with the GeoScript chapter_05/geo/populate_geo.sh, available in the code bundle for this book.

How to do it...

Search for documents in which the pin.location is 200 km away from latitude 40, longitude 70, as follows:

curl -XGET 'http://127.0.0.1:9200/test-mindex/_search?pretty' -d '{
  "query": {
    "filtered": {
