Why don't you use a simplified layer of administrative boundaries for your search? Or use a postgis table as you are using a huge layer data (Huge data is better and faster accessed in a postgis layer than in a shape file as the connection time is shorter than the request)? If you need great accuracy, I have no clue, sorry ;) Y. -- Yves Jacolin --- http://softlibre.gloobe.org
