I find no doc for the sort modifier. The only insight is in the unit tests: spec.lib.query.js#L12
writer.limit(5).sort(['test', 1]).group('name')
But it doesn't work for me:
Post.find().sort(['updatedAt', 1]);
In Mongoose, a sort can be done in any of the following ways:
Post.find({}).sort('test').exec(function(err, docs) { ... });
Post.find({}).sort([['date', -1]]).exec(function(err, docs) { ... });
Post.find({}).sort({test: 1}).exec(function(err, docs) { ... });
Post.find({}, null, {sort: {date: 1}}, function(err, docs) { ... });
