Las claves soundex tienen la propiedad que palabras pronunciadas de forma similar
|
|
producen la misma clave soundex y por lo tanto puede ser usada para simplificar
|
|
búsquedas en bases de datos donde se conoce la pronunciación pero no
|
|
la ortografía. Esta función soundex devuelve un string de 4 caracteres
|
|
de longitud, que inicia con una letra.

Esta función particular de soundex es la descrita por Donald Knuth
|
|
en "The Art Of Computer Programming, vol. 3: Sorting And
|
|
Searching", Addison-Wesley (1973), pp. 391-392.
