Checking for empty fields

I understand that I cannot query on the 'null' value for a field, and so
I should make null fields -1 instead.
 
About dynamic fields: is there a way to query for the existence of a
dynamic field?
 
Thanks,

You could use an open-ended range query:
For must exist:  myfield:[* TO *]
For must not exist: -myfield:[* TO *]
