[mkgmap-dev] How to search for the Second City Name

Hello list members, I have a doubt beginners Using this command: --x-split-name-index GPS or Mapsource I can search by street, by typing any part of her name. This facility also has the POI search, but the search for City not found a way to search only by the second name. Does anyone have a tip, if any, for this facility to be equal to search by street? grateful Carlos
