Search on blank ISBN
I know that I can search on ISBN because if I put an equal sign and a valid ISBN number from my database it comes up. How do I find all the ISBN fields that are blank? I have tried all the typical SQL commands for text fields but am unable to get any records back. I'm assuming that it is something to do with Python but can't seem to find an example of that.

Ok that did it. Was that update recently? I've looked at that page several times and don't seem to remember seeing the section on true and false.
