SOUNDEX Operator

Selects documents that include one or more words that "sound like," or whose letter pattern is similar to, the word specified. Words have to start with the same letter as the word you specify to be selected. For example, when you use SOUNDEX with "sale," the documents selected will include words such as "sale," "sell," "seal," "shell," "soul," and "scale." Documents are not relevance-ranked unless the MANY modifier is used.
