mongodb如何查找排除区域，$ geoExclusion？

Question

There is a $geoIntersection. But does it exist something similar to $geoExclusion? I would like to find polygons that do not intersect to certain areas.

Answer 1

Try using $not :

db.places.find({ "loc" : { "$not" : { "$geoIntersects" : { 
    "$geometry" : { 
        "type" : "Polygon", 
        "coordinates" : [[ [ 0, 0 ], [ 3, 6 ], [ 6, 1 ], [ 0, 0 ] ]] 
    } 
} } } })
