The dataset's size is several GBs, and this is how the data looks like:

{ "_id" : ObjectId("4d7a97c0ed7cd785fe37804d"), "p" : "n", "id" : 20973869, "c" : [ 288174269, 1024.00003 ], "r" : 890 } { "_id" : ObjectId("4d7a97c0ed7cd785fe37804e"), "p" : "n", "id" : 20973895, "c" : [ 288174614, 1024.00003 ], "r" : 41 }

This is the index:

db.nrwi.ensureIndex(

{ c: '2d', r: 1 }

,

{ min: 0, max: Math.pow(2, 30) }

)

To use this large 2d min/max work as explained in this post: http://groups.google.com/group/mongodb-user/browse_thread/thread/ef9047d0c94c0667
