If you want performance, a better way might be to assign some special
string/value (if it's easy to create) to the missing field of docs and
index the field without tokenizing it. Then you may search for that
special value to find the docs.

This is from Solr, so I'm not sure off the top of my head if this mojo

all documents that do not have the specified field.
