832 DESCRIPTION
833 This procedure finds the top terms of a thesaurus. A top term is defined
834 as any term which has a narrower term but has no broader terms. This
835 differs from TT in that TT takes in a phrase and finds the top term for
836 that phrase, but THES_TT searches the whole thesaurus and finds all
837 top terms.

844 NOTES
845 Since this function searches the whole thesaurus, it can take some
846 time on large thesauri. It is not recommend to call this often
847 for such thesauri. Instead, the application should call this once,
848 store the results in a seperate table, and use those stored results
849 instead.
