Location Lookup Bias
By default location lookups are biased toward the US. You can create a series of refinements by using the
$location_lookup_bias in config.php.
For example say you wanted to lookup Bayonne. By default Bayonne, New Jersey would be interpreted. If you were intended for France you would set your config as the following:
static $location_lookup_bias = "country:France";
A full listing of available bias options are available here: https://developers.google.com/maps/documentation/geocoding/intro#ComponentFiltering. You can use as few or as many as you want, by separating each set with pipe "|" character.
