>    Affects Versions: 2.17.1
>            Reporter: Kris Boutilier

> There is a often a requirement to fetch the min/max record from Mongo based on a particular field. Typically the operation is performed using syntax similar to:
>  db.collection.find().sort({_id: -1}).limit(1)
> or
>  db.collection.findOne({$query:{},$orderby:{_id:-1}})
> As implemented the findOneByQuery operation currently ignores the sortBy header. This trivial patch passes sortBy to the sort parameter of findOne(), if set.
> Helpfully, if the projection parameter is null findOne() returns all fields, so the state of fieldFilter is not checked before passing when the sortBy header has been set.
