Exact Match Search - town name must match letter for letter.

BMPM Soundex Search - Beider-Morse Phonetic Name Matching System is an algorithm developed by Alexander Beider and Stephen P. Morse to enable the searching of a list for names that are phonetically equivalent to the desired name. It is similar to a soundex search in that an exact spelling is not required. However unlike soundex, it does not generate a large quantity of false hits.

From the spelling of the name, an attempt is made to determine the language. Phonetic rules for that particular language are then applied to transliterate the name into a phonetic alphabet. If the original language cannot be deteremined with a fair degree of certainty, generic phonetic rules are applied.

D-M Soundex Search - If you are not familiar with the correct, contemporary spelling of the town name, try using the Daitch-Mokotoff soundex option which will provide a list of towns whose names sound like the name of the town you are seeking. For example, "SZCZUCIN", "SZCZECIN" and "SHCHUCHIN" would all be offered as search option if you enter the town name as "SZCZECIN".

Begins With Search - displays a list of all towns that begin with the entered letter combination (minimum of first three letters). For example, a search of BREST may return a list that includes BREST, BREST DISTRICT, BREST GMINA, BREST POVIAT, BREST REGION and BREST UEZD.
