We still need to show how to get a single result. But, I think we should remove this big `caution` spot (as you have), but then replace all `getSingleResult` in the docs with `getOneOrNullResult`. That method did not exist when I originally wrote this page - but it is much easier to work with (since it doesn't throw an exception on no results... though it does throw an exception if there are more than 1 result).
