Using a geo bounding box filter
One of the most common operations in geolocalization is searching for a box (square).
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...
A search to filter documents related to a bounding box (40.03, 72.0) and (40.717, 70.99) can be done with a similar query:
curl -XGET http://127.0.0.1:9200/test-mindex/_search?pretty -d '{ "query": { "filtered": { "filter": { "geo_bounding_box": { "pin.location": { "bottom_right": { "lat": 40.03, "lon": 72.0 }, "top_left": { "lat": 40.717, "lon": 70.99 } } } }, "query": { "match_all": {} } } } }'
How it works...
ElasticSearch has a lot of optimization options to search for a box shape. The latitude and longitude...
