first I attempted this by adding a predicate to the

is bound?
It might be worth trying to debug this before trying other options.
so combining a predicate with the binding should work?
A filter predicate should work, but not a fetch predicate.
an alternative to that would maybe be using coredata to store
copies of all the attributes I filter on in the arrangeObject in a
single NSData/binary field ....at least that would mean I would
only need to deserialise one property to do all the filtering.
I think that should work, assuming the understanding of the
performance problem area is correct. :)
