Does haystack have a exists(), similar to Django's queryset's exists()?

There are a lot of times when I just need to make sure that a result exists and perform some action according to that, but I have to call self.results.count() and check it's value. It seems like an unnecessary extra query to me. Django's querysets solve this by using queryset.exists(), does haystack have an equivalent method?

If not, I can look into adding such a method. I already use a mostly functional version of this method for my own classes, it can probably be refitted into haystack.
