Because metadata does not vary within a bucket, geo indexes on metadata can use an ordinary geo index on the time-series buckets collection.

For example,

{
	createIndexes: “abc”,
	indexes: [ { key: { “metaFieldName.a” : "2dsphere" } } ]
}

will become

{
	createIndexes: “system.buckets.abc”,
	indexes: [ { key: { “meta.a” : "2dsphere" } } ]
}

JS test code

assert.eq(1,
          timeseriescoll.aggregate([
              {$geoNear: {
                  near: {type: "Point", coordinates: [40.4, -70.4]},
                  distanceField: "dist",
                  spherical: true
              }},
              {$limit: 1}
          ]).toArray().length,
          "Failed to use 2dsphere index: " + tojson(twoDSphereBucketsIndexSpec));

Note: the same query on the corresponding buckets collection works fine, so the index is created via the time-series collection, we just can't use it.
