Take a look at ERXToManyQualifier.
Should be something like
EOQualifier q = new ERXToManyQualifier(Book.AUTHORS.key(),new
NSArray<Author>(author),0);
or using ERXQ
EOQualifier q = ERXQ.has(Book.AUTHORS.key(),new
NSArray<Author>(author));
NSArray<Book> matchingBooksSortedByName =
Book.fetchBooks(ec,q,Book.NAME.ascs());

Ok ok... I suck at writing examples as I incorrectly explained myself.
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,
new EOKeyValueQualifier(_Book.AUTHOR,

Hi,
How do I build a fetch specification that qualifies objects based
on the content of relationship and not an attribute?
In other words let's say I want all the records from the 'Book'
entity that have an 'author' relationship to a specific record in
the 'Author' entity.
