[mkgmap-dev] Address search confused by place=* with name,ref

Right, this would fix the problem for place=*. But, before fixing that, 
I would like to ensure that the boundary=administrative relations are 
working in a similar way.

I guess that the inc/names is not such a good idea for other than 
commercial POIs (shops, fuel stations, anything with a fee). The ref=* 
does make sense for roads, but operator=* (such as the maintenance 
operator) or brand=* probably do not. However, there is no problem for 
roads in the default style, because the 'lines' file is not referring to 
inc/names.

In Finland, street names are supposed to be unique within a municipality 
or city (admin_level=8). So, for the address index it would be best to 
only use the 'city' name from the boundary relations, and to ignore any 
suburbs or city parts. If I now search for Vantaa, I will find some 
streets located in the city. Other streets would have to be sought in 
city parts such as Vantaanportti and Vantaanlaakso. Hardly anybody would 
know all the city parts.

While the suburb or city part borders are useless for address search, 
they could still be interesting on the map display, because the Finnish 
'cities' typically contain many 'towns' separated by large areas of 
nearly uninhabited farmland or forest.

Another issue is that the boundary naming rule in 
styles/default/relations does not seem to have any effect any more. The 
boundary lines near my home are only listing one of the relation 
'owners' instead of showing all names that were added to 
mkgmap:boundary_name. The lines used to list all municipal or provincial 
borders (e.g., Kerava/Sipoo/Helsingin seutukunta/Itä-Uusimaa/whatnot).  
Now only one name is being shown at random. On the Finnish/Russian 
border, that name is 'Suomi' (Finland in Finnish) for a few sections of 
the border, but many sections have some transliterated label from some 
Russian boundary=administrative relation.

I wonder if it would be possible to define up to 4 labels for an 
administrative border, like for streets. If it is possible to show only 
one label for a border, it should be that of the municipality ('city'), 
not smaller (suburb or village) or bigger (province, state or country, 
if the municipality happens to be on a provincial border).

I think that it could make sense to define separate lines for interstate 
or international borders (so that the major border could be overlapped 
with a lesser border that belongs to the municipality or province 
bounded by the same line).

Best regards,
