keywords used by verity's thesaurus

["mp uc" <webforumsuser@xxxxxxxxxxxxxx>]

I want to use the thesaurus operator in verity to search my collection. 
Unfortunately, I need to re-purpose the results to fit another system, so I 
don't know what keywords verity is using from the thesaurus to produce the 
results.

 Is there a way to output the keywords used from verity's thesaurus?
