Comment (by svniemeijer):
This documentation fragment does indeed get to the core of what is
happening, but I still had to read it several times to understand the
difference. To me ''and'' and ''as well as'' mean the same thing.
It may be useful to refer to the concepts of union and intersection,
because the first example gives an annotation on the intersection of books
matching the two conditions whereas the second one gives an annotation on
the union of them.
