MongoDB - Geospatial queries - query order

I'm having a very strange problem with MongoDB Geospatial indexes:

> db.events.find({'geo': {'$maxDistance': 5, '$near': [45.21012750000001, 7.1364645]}})
error: {
"$err" : "geo values have to be numbers: { $maxDistance: 5.0, $near: [ 45.21012750000001, 7.1364645 ] }",
"code" : 13026

}

The weirdest thing is that the same query written in different order works perfectly:

> db.events.find({'geo': {'$near': [45.21012750000001, 7.1364645], '$maxDistance': 5}})

Shouldn't both queries hold the same result?

The two queries are not treated the same - as you saw, order matters.

There is a request to make the two identical in https://jira.mongodb.org/browse/SERVER-1990 but it's not currently targeted for a specific release.

Feel free to vote on the issue and/or watch it.
