MongoDB: Is it possible to make a case-insensitive query?

Example:

> db.stuff.save({\"foo\":\"bar\"});

1
> db.stuff.find({\"foo\":\"BAR\"}).count();
0

One very important thing to keep in mind when using a Regex based query - When you are doing this for a login system, escape every single character you are searching for, and don't forget the ^ and $ operators. Lodash has a nice function for this, should you be using it already:

db.stuff.find({$regex: new RegExp(_.escapeRegExp(bar), $options: 'i'})

Why? Imagine a user entering .* as his username. That would match all usernames, enabling a login by just guessing any user's password.
