[Geocoding] Strange results on local nominatim instance

[Knut Arne Bjørndal]

Hi

I'm trying to setup a nominatim instance to do some bulk geocoding of
Swedish addresses at work.

Everything seems to have worked quite fine, the indexing was done in a
morning and most results work just fine. However I'm seeing some
strange results. For example:

$ curl -s 'http://nominatim.openstreetmap.org/search?q=57001%20Rörvik%20Sävsjö&format=json&addressdetails=1'|json_xs 
[
   {
      "boundingbox" : [
         "57.2281896973",
         "57.248193512",
         "14.5645019913",
         "14.5845029449"
      ],
      "licence" : "Data Copyright OpenStreetMap Contributors, Some Rights Reserved. CC-BY-SA 2.0.",
      "lat" : "57.2381925",
      "display_name" : "Jönköpings län, Götaland, 57001, Sverige",
      "place_id" : "79669471",
      "address" : {
         "country" : "Sverige",
         "country_code" : "se",
         "administrative" : "Götaland",
         "postcode" : "57001",
         "state" : "Jönköpings län"
      },
      "lon" : "14.5745022",
      "class" : "place",
      "type" : "postcode"
   }
]

vs:

$ curl -s 'http://localhost/~bob/nominatim/search?q=57001%20Rörvik%20Sävsjö&format=json&addressdetails=1'|json_xs 
[
   {
      "boundingbox" : [
         57.2341499328613,
         57.2424201965332,
         14.568359375,
         14.5801544189453
      ],
      "licence" : "Data Copyright OpenStreetMap Contributors, Some Rights Reserved. CC-BY-SA 2.0.",
      "lat" : 57.2381925,
      "osm_id" : 946957017,
      "osm_type" : "node",
      "display_name" : "37, Jönköpings län, Sweden",
      "place_id" : 78456,
      "address" : {
         "country" : "Sweden",
         "hamlet" : "Hillafällan",
         "country_code" : "se",
         "administrative" : "Sävsjö",
         "county" : "Jönköpings län",
         "state" : "Jönköpings län"
      },
      "type" : "postcode",
      "lon" : 14.5745022,
      "class" : "place"
   }
]

And:

$ curl -s 'http://nominatim.openstreetmap.org/search?q=Enköping&format=json&addressdetails=1&limit=1'|json_xs 
[
   {
      "icon" : "http://open.mapquestapi.com/nominatim/v1/images/mapicons/poi_boundary_administrative.p.20.png",
      "boundingbox" : [
         "59.3833923339844",
         "59.8847732543945",
         "16.7275142669678",
         "17.5420475006104"
      ],
      "licence" : "Data Copyright OpenStreetMap Contributors, Some Rights Reserved. CC-BY-SA 2.0.",
      "lat" : "59.6632645977182",
      "osm_id" : "308557",
      "osm_type" : "relation",
      "display_name" : "Enköping, Södermanlands län, Uppsala län, Svealand, Sverige",
      "place_id" : "79468260",
      "address" : {
         "country" : "Sverige",
         "country_code" : "se",
         "administrative" : "Enköping",
         "county" : "Södermanlands län",
         "state" : "Uppsala län"
      },
      "type" : "administrative",
      "lon" : "17.1434570925975",
      "class" : "boundary"
   }
]

vs.

$ curl -s 'http://localhost/~bob/nominatim/search?q=Enköping&format=json&addressdetails=1&limit=1'|json_xs 
[
   {
      "icon" : "http://james.adm.easyconnect.no/~bob/nominatim/images/mapicons/poi_boundary_administrative.p.20.png",
      "boundingbox" : [
         59.3833923339844,
         59.8847732543945,
         17,
         17.5420475006104
      ],
      "licence" : "Data Copyright OpenStreetMap Contributors, Some Rights Reserved. CC-BY-SA 2.0.",
      "lat" : 59.6632645977182,
      "osm_id" : 308557,
      "osm_type" : "relation",
      "display_name" : "Sweden",
      "place_id" : 704456,
      "address" : {
         "country" : "Sweden",
         "country_code" : "se"
      },
      "type" : "administrative",
      "lon" : 17.1434570925975,
      "class" : "boundary"
   }
]

Looking at this last one I find the same OSM object but for some
reason it's labeled "Sweden" instead of the name of the municipality.

The detail page say this about place_id 704456:
Name:
Enköping (name)
Type: boundary:adminitrative
Admin Level: 7
Rank: County
Coverage: Polygon
OSM: relation 308557

The code and data is the latest from svn and geofabriks Sweden extract
as of last monday.

Any ideas on how to further debug this?
