I have the following documents
/* 0 */
{
"_id" :
{
"rowId" : "d8a908fc-c549-4485-8610-c2893334211e",
"a" : "0"
}
,
"Updated Time" : ISODate("2013-09-24T14:26:02.288Z"),
"geoPoint1" :
{
"coordinates" : [
-122.8112,
38.8047
]
}
}
/* 1 */
{
"_id" :
{
"rowId" : "c7851807-6107-4262-bb26-711c8902a7c4",
"a" : "0"
}
,
"Updated Time" : ISODate("2013-09-25T01:43:56.400Z"),
"geoPoint1" :
{
"coordinates" : [
-116.444,
33.429
]
}
}
/* 2 */
{

"geoPoint1" :
{
"coordinates" : [
-148.8046,
62.9881
]
}
}
If I run
db['dbname'].find({},
{ _id: 0, "Updated Time" : 1, "geoPoint1.coordinates" :1}
) I get back all the documents without the ID as expected
/* 0 */

If I do db['dbname'].find({},
