Ok guys makes perfect sense and jives with my removal of @Indexed halfway
through the development of my project, which I did do. I only did that
because I read this in the objectify documentation, and I was cruft cutting

"By default, all entity fields except Text and Blob are indexed. You can
control this behavior with @Indexed and @Unindexed annotations on fields or
classes:"

http://code.google.com/p/objectify-appengine/wiki/IntroductionToObjectify

Maybe I misinterpret something somewhere, but either way I am glad I won't
have to switch to simple DB. I will do the mapreduce putting
