[mkgmap-dev] Improved street search in index branch

Hi Steve,

you are doing a great job!

I tested the latest index branch, compiled a map of germany with the 
default style and tried some searches in MapSource.

* Searching for streets works fine for me.
* Searching for streets and cities does not work (error message from 
* Searching for crossroads works most of the time. But I made an 
interesting observation:
If you search for a crossroads of two residentials and one of the 
residentials also exists as track (with the same name), the crossroads 
is not found. Example: Lesumstrasse and Valmeweg 
I have also tried other examples. Sometimes it works and sometimes not. 
Maybe the problem is that the street is cut in more than one part.
