Thesaurus Option Setting


This setting specifies the thesaurus operator that will determine the type of expansion performed, when an end user specifies a thesaurus filename. To turn on thesaurus searches of this kind, the end user wraps a word with brackets ([]). The valid values you enter for this property are listed in the following example. This setting is used for all instances of the search whenever a search term is enclosed within brackets ([]).

Example

Property: Thesaurus Option

Value: WORD_SUFFIX

Possible properties and the effects for the usage of the Thesaurus appear in Table 36.

WORD_SYNONYM

Includes the synonyms defined in the thesaurus

WORD_SUFFIX

Expands the word or phrase to include their plural and possessive forms. For example, if you search on the word, DISK, the results returned would include DISKS and DISK'S.

WORD_SIMILARITY

Uses a combination of the WORD_SYNONYM and WORD_SUFFIX options. This option gives the synonym processing priority over the suffix processing. If there is a synonym match, there is no further search for an additional suffix match. However, if there is no synonym match, then suffix processing is performed.

WORD_MODIFY

Uses the linguistic processing filter to expand searched terms. This filter and its related options are specified in the thesaurus file parameter of this function. For example, if you use the international filter with the linguistic rules filter enabled and search on the word DISK, the following actions occur: First the term is expanded through the international thesaurus filter, and then the resulting synonyms are run through the linguistic filter rules filter to be inflected. For more on this setting, see Search Term Generator Setting.

WORD_BROADEN and WORD_NARROW

equivalent to the WORD_SYNONYM option. These settings are included for clarity if the thesaurus file specified in the function is intended to broaden or narrow the term specified. For example, if you search on DISK, the results returned would include DISC, AND DISK.
