Well, does Query.h/Query.c need to know about every object (e.g.
Transaction, GncCustomer, Split, GncEntry, etc) or is it a
framework so that each new object can "plug in" its own query
terms?

True, but where do you find the query terms for the different
kinds of objects?

My issue is that currently the code in src/engine knows nothing
about the business objects.  I'd like to keep it that way.
Unforutnately the Query is the current sticking point.
