 1. The query "44 Clarence Avenue Southeast, Minneapolis, MN 55414, USA"
 does not point directly to the house, even though the house is clearly in
 the system. The closest it comes is the beginning of Clarence Avenue, but
 the result displays the incorrect ZIP code (55114 instead of 55414; 55114
 is located in St. Paul, and 55414 is located in Minneapolis; the boundary
 between St. Paul and Minneapolis is the north-south street Emerald Avenue,
 a bit to the east of the above address.)

 2. The query "44 Clarence Avenue Southeast, Minneapolis, MN 55414-3528,
 USA" returns no results at all; the only difference is the inclusion of
 the "-3528" carrier code to the ZIP code.

 3. The query "44 Clarence Avenue Southeast, Minneapolis, MN 55114, USA"
 DOES point directly to the correct house, even though this is the
 incorrect ZIP code. It seems that the ZIP code's boundaries are incorrect.

 My hunch is that the problem stems from incorrect ZIP code boundaries.
 West of Emerald Avenue is Minneapolis (55414), while east of Emerald
 Avenue is St. Paul (55114).
