      curl -sSL https://gist.github.com/jaymecd/71224330eaf6bfbb5676/raw/tzdoc.json | mongoimport -d mydb -c timezone --upsert

      3) run command w/o uniqueDocs - see warning

      db.timezone.aggregate([ { $geoNear: { near: { type: "Point", coordinates: [ -84.198026746273, 39.89626511522 ] }, spherical: true, maxDistance: 50002, distanceField: "dist" } }, { $limit: 2 }, { $sort: { pos: 1, dist: 1 } }, { $match: { pos: 1 } }, { $project: { _id: 0, iso: "$cco" } }, { $limit: 1 } ]);

      4) check logs and find warning

      $geoNear pipeline within aggregate command always logs a warning about deprecated option "uniqueDocs" (see below), even if that option has never been set or used.

      mongodb.log:

      warning: mydb.timezone: ignoring deprecated uniqueDocs option in geoNear command

      As I get right, aggregation command calls first GeoNear command with always set "uniqueDocs" option.
