There are numerous formats available to pass a geo bounding box to the elastic search API. One of those methods in the bounding box as well-know text or WKT for short. For what ever reason I find string easier to pass and manage in redux state, so I’m using the well-know text. Now I couldn’t find the ordering of the polygon in the string, so here it is:
...
"filter": {
"geo_bounding_box": {
"pin.location": {
"wkt": "BBOX (-74.1, -71.12, 40.73, 40.01)"
...
/*
the order of the coordinates is:
right, left, top, bottom (assuming you're looking at a standard map, north at the top, east on the left)
or
min longitude, max longitude, max latitude, min latitude
or
west bound, east bound, north bound, south bound
*/
If you find this documented somewhere else please let me know. There are some edge cases I haven’t tested like when a bounding box overlaps the prime meridian and equator. I’ve saved this mostly for my memory and reference, I hope someone else finds it useful. I’ll try to update if I find anything different.
