Well, as I said there, you can match author's names.  You wouldn't match
Hanson, C with Hanson, Chris even if they were the same person, but you
could match all instances of Hanson, C.  Even if they weren't the same
person, they'd be indistinguishable at this level.

I did say that I'm not sure where that would come down on the
performance/memory use equation, though.  I haven't done a multi-way search
on a managed object context with > 10000 objects yet.  Anyone know how quick
that is?
