thinking that the main issue here is exploding index and I'm not sure
how to get around that other than to cut search features from the

You might want to check Query filters here:
http://code.google.com/appengine/docs/java/datastore/queriesandindexes.html#Introducing_Queries
a query can only have one not-equal filter, and such a query cannot have
other inequality filters
A workaround can be to add two extra boolean properties

There probably is a design that will allow you to accomplish what you need

Your approach works fine for me on OS X. But the datastore is held in
memory so only one app can use it at a time. If you make changes to
the datastore you also need to wait until you see the log message

Since the datastore doesn't support joins, it's generally advantageous
to denormalize your data where possible and use fewer tables than you
would in a relational model. It seems fairly unlikely that most data
would move nicely from 30 tables into a single one, although it's hard
