When I run this query using the C# driver:

"{ \"Location\" : { \"$within\" :

{ \"$centerSphere\" : [[-74, 40.74], 1] }

} }"

I get this error:

MongoDB.DriverOnlineTests.MongoCollectionTests.TestFindWithinCircleSphericalTrue:
MongoDB.Driver.MongoQueryException : QueryFailure flag set: Spherical distance would require wrapping, which isn't implemented yet (response:

{ "$err" : "Spherical distance would require wrapping, which isn't implemented yet", "code" : 13462 }

)

Here's the same error reproduced in shell:

> use onlinetests

> db.testcollection.find()

{ "_id" : ObjectId("4d3f20f0e447ad602837252f"), "Location" : [ -74, 40.74 ], "Na me" : "10gen", "Type" : "Office" } { "_id" : ObjectId("4d3f20f0e447ad6028372530"), "Location" : [ -75, 40.74 ], "Na me" : "Two", "Type" : "Coffee" } { "_id" : ObjectId("4d3f20f0e447ad6028372531"), "Location" : [ -74, 41.73 ], "Na me" : "Three", "Type" : "Coffee" }

> db.testcollection.find({ "Location" : { "$within" :

{ "$centerSphere" : [[-74, 40.74], 1] }

} })
error: {
