Using the Thesaurus

The ondisc Thesaurus comprises two main sections: the List of Permuted Terms and the Term Details. The List of Permuted Terms is an alphabetical list of all the controlled vocabulary terms used to index records in the database.

The Term Details for a given term may contain Narrower terms, Related terms, Broader terms, Scope notes, and Used For notes. Use narrower terms to focus your search; use broader and related terms to broaden your search.

The Explode function on the Term Details screen will search for the main descriptor and all its narrower descriptors. To narrow your search, use the most specific descriptor for the concept.
