In support of our SCRUM practices, I've introduced a couple custom columns to my issues (iteration, points). I want to be able to get issues from the api that do not have a null value for one or both of those columns.

In effect, I want a 'not null' filter for getting data in the criteria object.

As it is right now, I have to dump all the issues in the db into a memory and then run a linq query on the List. Not efficient.
