The relationship is a toMany so... rewording my request:
I want all the records from the 'Book' entity that have an 'authors' relationship that CONTAINS a specific record coming form the 'Author' entity.

Hi,
How do I build a fetch specification that qualifies objects based on the content of relationship and not an attribute?
