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
