Newbie question: value inequality in Manager Method?

[BobAalsma]

In models.py, when I use
class GevondenManager(models.Manager):
        def get_query_set(self):
                return 
super(GevondenManager,self).get_query_set().filter(crcWaarde
= 0)
I get proper answers.

However, I want to filter on "not equal to" and this does not seem to
work. How to proceed?

I have tried
class GevondenManager(models.Manager):
        def get_query_set(self):
                return 
super(GevondenManager,self).get_query_set().filter(crcWaarde
<> 0)

as well as
class GevondenManager(models.Manager):
        def get_query_set(self):
                return 
super(GevondenManager,self).get_query_set().filter(crcWaarde !
= 0)

and in both cases the results seem the same:
