Thomas Champagne commented on SOLR-2982:
----------------------------------------
I noticed too the bad performance of Beider Morse encoder. So, I have created
an issue CODEC-174 in the commons-codec project to improve the performance.
Currently, I have created two patches that allow dividing the encoding time by
2.
If you want a better Beider Morse encoder, you can join us on the issue
CODEC-174 :)
> Upgrade Apache Commons Codec to version 1.6 in order to add new Beider-Morse

> Apache Commons Codec released version 1.6 of their codec pack in November,
> 2011. Along with a few bug fixes, 1.6 contains a great new phonetic matching
> system called Beider-Morse Phonetic Matching (BMPM) that is far superior to
> the existing phonetic codecs, such as regular soundex, metaphone, caverphone,
> and so on. BMPM has actually been available for some time, but this is the
> first port of it to java, and its first commit in the Apache ecosystem.
> For a lot more information, see here: http://stevemorse.org/phoneticinfo.htm
> and http://stevemorse.org/phonetics/bmpm.htm
> BMPM would be a fantastic "soundalike" tool to help search for personal names
> (or just surnames) in a Solr/Lucene index, much better than Levenshtein
> distance for this use case.
