Elasticsearch geo_bbox with Google Places API viewport locations - google-maps-api-3

Question

Hopefully I can explain my issue.
I am using Google's Autocomplete to get a person destination. Once I have the destination I can use google's place api to look up the geometry viewport. But the viewport is from theNorth/East to South/West. My problem is with Elasticsearch the geo_bbox takes it from top/left to bottom/right. See examples below.

},
"filter" : {
"geo_bounding_box" : {
"pin.location" : {
"top_left" : {

},
"bottom_right" : {
"lat" : 40.717,
"lon" : -73.99
}
}
}
}
}
}
Is there a better way to get more info from google or can elasticsearch work from alternate corners. Although the docs does not say this?

Answer 1

Oh dear how thick I am.
All I needed to do was swap the result's around for my elastic search. ie,
{
"filtered" : {
"query" : {
"match_all" : {}
},
"filter" : {
"geo_bounding_box" : {
"pin.location" : {
"top_left" : {
"lat" : result.northeast.lat,
"lon" : result.southwest.lon
},
"bottom_right" : {
"lat" : result.southwest.lat,
"lon" : result.northwest.lon
}
}
}
}
}
}

If you know the North East and South West corners, you can calculate the North West (top left) and South East (bottom right) corners:
var NE = bounds.getNorthEast();
var SW = bounds.getSouthWest();
// calculated points
var NW = new google.maps.LatLng(NE.lat(), SW.lng());
var SE = new google.maps.LatLng(SW.lat(),NE.lng());
