[mkgmap-dev] multi-word street search

Wed Dec 10 01:25:41 GMT 2014

Hi Steve,

I have tested mixed-index branch and it doesn't work for me. Mkgmap 
creates bigger index file but search work the same in Mapsource, no 
results when searching for partial label. I'm not able to find the 
reason. I think function writeSectData doesn't save partial labels, but 
I can't tell if this is a problem.

I haven't tested in device.

I have modified a bit my version to test some other ideas, patch is 
attached. I have removed text in parenthesis form partial search, added 
split at hyphen and excluded numbers at the end of label.

-- 
Best regards,
Andrzej
