Hi

Folks, as you know – this comes up time to time – address search is
unpractical in most Latin countries where the street/square name usually
starts with the type (Via, Viale,Corso, Piazza etc [IT]; Avenida,
Calle, Plaza etc [ES]; Avenue, Boulevard, Rue, Place etc [FR] etc.)
followed by the full name of - usually - the person naming the street.
Nevertheless the street names sometime appears abbreviated (V.le,
Av.da, Bld. etc), sometime the Middle name is skipped, sometime the
work “of” is used (Avenue de Bobigny, Corso del Popolo etc)

The Garmin index format has a way of dealing with this problem and
earlier this year I made a branch that creates an index with the extra
information to show where the interesting part of the name starts.

The latest version indexes every word in the name separately so you
could find 'corso del popolo' by typing 'corso' , 'del' or 'popolo'.

So this will always work for any language, but at the cost of a
much larger index.

It would be great if someone could try it out as it is, then
if useful, its more likely that someone would improve it. By
devising a suitable way to cut down the useless entries.

Download it as mkgmap-mixed-index-r2662.jar at the bottom of the download
page.

So what is a simple Mozartstrasse in Austria would look like “Via
Wolfgang Amadeus Mozart” in Italy or “Rue Wolfgang Amadeus Mozart” in
France but possibly also “Av.da de Mozart” etc.

Now, everyone knows the street/square by its last name and it would be
much more practical to search by it: I’d like to have a style that just
pick the last full word of the street/square name and put it as a suffix
followed by a comma and the original name.

This would really boost address search for Latin countries – so it might
be a default style to add to IT, FR, ES, BR, MX… etc).

Could you help me on making that regular expression for the style?

“str1 str2… strN” -> “strN, str1 str2… strN”

Thanks!

Enrico

First result with the mixed-index branch, processing Spain with default style

Apart from the numbers, the address search doesn't work by now. Entries in the index are not unique and are not ordered (see screenshot 1). When you type a letter search results don't change accordingly (screenshot 2). This is the console output, if it is of any help:
=== FIRST
t1=0, t2=55013
first av 96203/24, last 0/12
AVENIDA : 32380
CAMINO : 14816
PLAZA : 12864
CARRETERA : 28180
CALLE : 288500
RÚA : 9130
CARRER : 117140
AVINGUDA : 11602
=== LAST
KALEA : 9682
AUZOA : 11604

I have compiled the same input data with the same command and strangely now it seems to work better. Typing "C" in the search field selects all streets with a "C" as first letter in their name after calle, avenida or whatever (see screenshot), apart from the 3 first entries in the list.
