How best to screen out stocks with poor debt-related fundamentals?

I've been playing with Zack's screener tool and I really like the ability to dial in what I'm targeting. I'm curious how I should evaluate debt numbers though? There's obviously good debt and bad debt and being able to distinguish between the two when running a scan is essential. Can you guys provide any pointers or tactics that you employ? Thanks.
