Re: Fluent API addition request

FWIW, when I need something like this for the WHERE part of a query I do it
with the ternary operator and a static import of ExpressionFactory (which
your IDE can add for you), like:

.and(yearRange != null ? APPOINTMENT_DATE.gt(yearRange) : expTrue())

I don't think there is a good alternative to handle prefetches, but this
handles the WHERE clause very well in my opinion.
