Hi Sarah,
I tried to follow your instructions. The importing of the relation
seemed to go fine. When I attempted to verify that I could find the
state with the a search query, I believe the original node for PA came
back and not the imported relation. Does this mean that my OSM data is
broken?

I also attempted a solution by expanding my import scope by using a
North America (complete US and Canada) file from
http://download.geofabrik.de/, and the results were the same. It seems
like at least for the US, these extracts are not very well suited for
Nominatim import. My next attempt will be to load from a complete planet
file.
Thanks,
John

Hi,
I have a local Nominatim instance with a US/Pennsylvania extract
loaded. When a make reverse geocode requests, I never get a state
back unless the coordinates are close to the centroid of the state.
It's most likely that the extract was cut a bit tight and didn't include
the full state boundary. You can add it to your database after the import
like this:
* Find the relation of Pennsylvania on the osm website and note the ID
(it's that http://www.openstreetmap.org/relation/162109)
* Import the relation to your database like that:
./utils/update.php --import-relation 162109 --index
* Verify that you can find the state now and it will give you back the
relation. Sometimes OSM data gets broken and then this part will fail.
* When all is well, you have to reindex everything.
Mark for indexing:
psql -d nominatim -c "select place_force_update(place_id) from placex
where osm_type = 'R' and osm_id = 162109"
And reindex:
./utils/update.php --index --index-instances 2
The last part is really slow, I' m afraid. You can also simply reimport
the database with an extract that is a bit larger than the state you need.

I am aware that the openstreetmap version of Nominatim always
returns valid results for my test coordinates, so what am I doing
wrong?
for example...
http://myserver/nominatim/reverse.php?format=xml&lat=40.658773&lon=-75.295520
returns
