From initial testing, it appears that if documents have the same terms and you included them in like and unlike, they cancel each other out and no documents are returned. Can this be confirmed as expected behavior?

For example, like document 1 contains "apple".  
unlike document 2 also contains "apple".

Zero results are returned.
