Last time about 20% on queries with small result sets.  It is a lot
worse for searches like 'Main Street' because there are now 1000s of
results rather than 100s.  It should be possible to claw a lot of that
back with partitioning of the data but that is still a TODO.

Main purpose of this parse is to test international support and
incremental updates.  I'm expecting to get a LOT of bug reports for
international character sets and the like, although I hope I've at
least fixed the various German problems from last time.
