SOUNDEX

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.

In order to be able to search in collections using the SOUNDEX operator, all documents must have been indexed with the Soundex option. This option can be added to the WORD-IDXOPTS parameter in the style.prm file. Afterwards all documents must be reindexed.

For example, to retrieve documents containing a word that is close in structure to the word "sale", you can enter the following:

<SOUNDEX> sale

The documents retrieved will include words such as "sale", "sell", "seal", "shell", "soul", and "scale". Documents are not relevance-ranked unless the MANY modifier is used, as in:

<MANY><SOUNDEX> sale
