Soundex is sometimes referred to as "Jewish Soundex" and "Eastern European Soundex", although the authors discourage use of these nicknames for the algorithm because the algorithm itself is independent of the fact that the motivation for creating the new system was the poor result of
78:
Multiple possible encodings can be returned for a single name (traditional
Soundex returns only one encoding, even if the spelling of a name could potentially have multiple pronunciations)
214:. This new algorithm cuts down on false positives at the expense of some false negatives. A number of sites are offering the B–M soundex in addition to the D–M Soundex.
75:
Several rules in the algorithm encode multiple character n-grams as single digits (American and
Russell Soundex do not handle multi-character n-grams)
293:
69:
Coded names are six digits long, resulting in greater search precision (traditional
Soundex uses four characters)
