The missing and wrong first letter feature enables GeoStan to look for the correct first letter of a street address if the first letter is missing or incorrect. GeoStan searches through the alphabet looking for possible, correct first letters to complete the street address.
The feature is disabled by default. To enable this feature, modify GS_FIND_FIRST_LETTER_EXPANDED.
