If a road has a name or reference it will have an entry in the address search data structure. It needs also to have a city associated with it which can either be the nearest city (town, village, etc.) or the road can be tagged explicitly using an is_in tag.
If I remember correctly, someone mentioned that roads may have a postcode associated with them. Is that true? Would it use the addr:postcode attribute of the way? Would it make sense to have an addr:city way attribute override an is_in attribute? Sometimes, post offices have different names from the city or town. The post office name would be more useful than the city name. I haven't added is_in or addr:* tags to ways yet; only to POIs. So, my map gets the city information from the nearmost "place" point on the map. Recently, I added addr:* to all shop=bicycle in Finland. I'm also going to add phone and url, but unfortunately, download.geofabrik.de (my source of finland.osm) has been unreachable since Friday. Marko
