Search Appliance
This area allows you to upload one or more custom thesauruses (synonym lists) for use by search profiles. An uploaded thesaurus is compiled and kept on the Search Appliance. You can download the thesaurus later by clicking on it in the listing.
Each thesaurus may be used by zero or more profiles and should not be deleted if
it is in use by a profile. Search options that affect the use of these thesauruses
are Synonyms(3.6.63),
Main Thesaurus(3.6.64), and
Secondary Thesaurus(3.6.65).
See section 4.3 for further details.
