1. soundex text> An algorithm for encoding a word so that similar sounding words encode the same. The first letter is copied unchanged then subsequent letters are encoded as follows: bfpv -> "1" cgjkqsxzþ -> "2" dt -> "3" l -> "4" mn± -> "5" r -> "6" Other characters are ignored and repeated characters are encoded as though they were a single character. Encoding stops when the resulting string is four characters long, adding trailing "0"s if it is shorter. For example, "SMITH" or "SMYTHE" would both be encoded as "S530".
