Several algorithms can be used for phonetic blocking. The fuzzy library provides all of them, but has a bug in v1.2. (see https://github.com/yougov/fuzzy/issues/14) that prevents soundex from working correctly. Unfortunately, that's the only version compatible with Python 3. Previously, version 1.1 was used on Python 2 and an alternative implementation of double metaphone was used on Python 3, so soundex and NYSIIS were not available. Now we install version 1.1 on Python 2 and 1.2. on Python 3, resulting in NYSIIS being always available also (this happens to be the algorithm giving the best results).
