If you have a query base portlet and a date in it, you just set the date as a filter field and specify that to be date range.
It will filter the items that do have the date in that range.
How do do the opposite?
How do you create a filter which returns the items that do not have a date in that range ie blank or other date?
I could think that using parameters I would need two which would give two date boxes which would appear to the user somewhat similar as the date displayed as a range so that it would not bee too different.
Is there a way to do that without parameters just using the date field?
