One approach to look for everything, or not something is to add a field to each document which is a constant value. Like a field named exists and a value of true.
Then you can do search like
exists:true NOT microsoft
This will find all documents without the term microsoft in them.
Just to have it find documents with nothing might be a little tricky. You might want to put a field in the document which indicates the size or something like that. Or just create an empty field and look for
empty:true
I hope this rambling helps
