I am trying to search duplicate records for a custom Object. I used "Soundex algorithm" for that, but it is not that much effective. So I want to do a search based on "Metaphone" algorithm. Can anyone help me to write a code for this algorithm in apex. I got a link http://arungaikwad.wordpress.com/2013/02/13/phonetic-search-in-salesforce-com/ but it does not help me.

Thanks in advance.
