Collection null search

In the advance search dialog I can perform a tag = null search but the collection requires a value. I'd like a null search so as I'm building my Zotero library with my 500+ old pdfs I can find the ones that I have not yet put into at least one collection.

I've used a lot of software and I'm no longer easily impressed. Zotero is AWESOME!
