[mkgmap-dev] Again on address search in latin countries

Mon Sep 19 17:21:36 BST 2016

I see some issues with your approach. First of all, I don't agree last 
word is the meaningful one, at least for Spanish. I can think of many 
real street names where it is not true.

If I got that right, your rule for label:3 won't give the expected 
result for special cases treated in previous lines. For example, "Via 
Vittorio Emanuele XI" would became "Emanuele XI, Via Vittoria Emanuele "

And for label:4, removing first word would also give wrong names in many 
cases, where the type of way (Via, Rue, Avenida, etc) is followed by 
some articles or prepositions, which is very common. For example, 
Avenida de la Libertad would became "de la Libertad", which doesn't make 
much sense and is not very useful for search. For these cases it could 
be useful to have a list of "street names beginnings" to be removed (eg. 
Calle, Calle de la, Calle de el, Calle del, Calle la, Calle, el, etc.)
