When you are working with geo locations, one of the common tasks is to filter results based on its distance from a location. The geo_distance filter is used to achieve this goal.
You need a working ElasticSearch cluster and the data populated with the geo populate script.
Searching documents in which pin.location is 200km distant from the lat value 40 and the lon value 70, is done using a similar query as follows:
curl -XGET 'http://127.0.0.1:9200/test-mindex/_search -d '{
"query": {
"filtered": {
"filter": {
"geo_distance": {
"pin.location": {
"lat": 40,
"lon": 70
},
"distance": "200km",
"optimize_bbox": "memory"
}
},
"query": {
"match_all": {}
}
}
}
}'
