[mkgmap-dev] Only one Friedrichstraße in Berlin could be found

Hello, I already sent this to the list, but maybe it was somehow lost. http://www.mkgmap.org.uk/pipermail/mkgmap-dev/2011q4/013071.html With Version 2097 I was able to find more than one Friedrichstraße (Lichterfelde 12205, Spandau 13585 and Mitte 10117) in Berlin. With Version 2098 I only could found one Friedrichstraße (in Spandau) (but I can find them if I have just one tile on my Garmin and do not enter the city (http://youtu.be/8WETq30IFJ4)). My idea was, to create for every Friedrichstraße, which has a different zip-code, an entry in the index. I do not really know how the index work (is there any documentation?!), but as I said, it's just an idea. Cheers, Martin
