This probably isn't namefinders fault, but I just tried searching for
OX1 3HZ on the OSM home page, and I was taken to the wrong place,
several miles north of Oxford. It seems npemap.org.uk gives the same
result. Where is it getting this from?

When I tried it on http://www.frankieandshadow.com/osm/, it tells me
that it cannot find Frewin Chambers, Frewin Court, Oxford (which is the
correct place, and is "correctly" not found because it isn't on the map).

I should be presented with the best guess location based on averaging
the results of just the start of the postcode - OX1 3**, at a low-ish
zoom level, and with a message that id can't find the exact place.

Ideally something should cache the information that there is a place
called Frewin Chambers, Frewin Court, Oxford in the OX1 region that
needs to be found and added to the map.
