ezFind empty field

Hi,

I'm filtering my articles in the way you don't see ones that are expired, It looks similar to this:

[1]   {set $filter = $filter|append('article/unpublish_date:[NOW/DAY-100DAY TO NOW]')}

This is supposed to print out all the articles that are expired (not older than 100 day). Now, It works ok. When I want to printout only those that are not expired I use something like this:

[2]  {set $filter = $filter|append('article/unpublish_date:[NOWTO NOW/DAY+100DAY]

Also, works ok. The problem: I have a lot of articles with unset attribute unpublish_date. So the filter 2 prints only the ones that have unpublish_date set. (therefore this question essentialy means, can I do something like this?:)

{set $filter = $filter|append('article/unpublish_date:[" "]')} -> not working :)

Is there a way to print out and those ones that have this field empty? If I need to set unpublish_date to all the early articles (when default value was not set) I will shoot myself :)

tnx
