Here is an example collection db.geo_json_test.insertMany([{name: "00A", location: {type: "Point", coordinates: [-81.09670311007132, 46.575020657518266] }},{name: "147", location: {type: "Point", coordinates: [-81.067788, 46.3822689] }},{name: "001", location: {type: "Point", coordinates: [-92.16504975147868, 66.85083025648714] }},{name: "002", location: {type: "Point", coordinates: [-80.9422811, 46.512260000000005] }},{name: "000", location: {type: "Point", coordinates: [-80.942295, 46.51226270000001] }},{name: "008", location: {type: "Point", coordinates: [-81.09670311007132, 46.575020657518266] }},{name: "007", location: {type: "Point", coordinates: [-81.09653748648944, 46.575012427925024] }},{name: "006", location: {type: "Point", coordinates: [-81.0972791024576, 46.57375187851832] }},{name: "005", location: {type: "Point", coordinates: [-81.101199979413, 46.56988771702767] }},{name: "004", location: {type: "Point", coordinates: [-81.05537133207827, 46.56975708845099] }},{name: "003", location: {type: "Point", coordinates: [-81.09831646261244, 46.57729676918206] }},{name: "02", location: {type: "Point", coordinates: [-81.07875689437888, 46.56184186179797] }}])   The following query to the collection returns all points db.geo_json_test.find({'$and': [{'location': {'$geoWithin': {'$geometry': {'type': 'Polygon', 'coordinates': [[ [-13, 71] , [-161, 71] , [-161, 16] , [-13, 16] , [-13, 71] ]]}}}}]})   However, the following query which is changing the longitude by 1 unit further to the east returns only one point. This polygon is a little bigger than the previous one and should include all the points that were included in the previous one db.geo_json_test.find({'$and': [{'location': {'$geoWithin': {'$geometry': {'type': 'Polygon', 'coordinates': [[ [-12, 71] , [-161, 71] , [-161, 16] , [-12, 16] , [-12, 71] ]]}}}}]})
