GeoParser::parseGeoJSONPolygon validates geodata as part of indexing. If a document has a "bad" or unsupported geometry uasserts are thrown like:
uassert(16693, "Exterior shell of polygon is invalid: " + obj.toString(),
exteriorLoop.IsValid());
Resulting in a message like:
{
"singleShard" : "docs/bartleby.local:30000,bartleby.local:30001,bartleby.local:30002",
"err" : "Exterior shell of polygon is invalid: { type: \"Polygon\", coordinates: [ [ [ -97.41583300000001, 40.002001 ], [ -97.41782600000001, 40.002024 ], [ -97.425443, 40.002048 ], [ -97.44466199999999, 40.001958 ], [ -97.463285, 40.002047 ], [ -97.51026400000001, 40.001835 ], [ -97.511381, 40.001899 ], [ -97.515308, 40.001901 ], [ -97.767746, 40.001994 ], [ -97.769204, 40.001995 ], [ -97.770776, 40.001977 ], [ -97.77715499999999, 40.002167 ], [ -97.81942600000001, 40.001958 ], [ -97.821496, 40.002002 ], [ -97.82081599999999, 40.350545 ], [ -97.370694, 40.350312 ], [ -97.36868800000001, 40.350392 ], [ -97.36919899999999, 40.00206 ], [ -97.36919899999999, 40.00206 ], [ -97.41583300000001, 40.002001 ] ] ] }",

…only the relative geometry document is returned, not the entire document nor the _id field.
Compare to :
db.counties.ensureIndex({"geometry.coordinates": "2d"})
which returns:
