Unfortunately, not yet. This version is a demonstration of the planned professional Hungarian thesaurus developments for OpenOffice.org 3. Now it contains the most frequent Hungarian words and their synonyms (a few hundred words) and Unicode and calendar demo data. I think, for a successful OpenThesaurus project needs a free base dictionary (we will work on it) and a huge user base (this is a question for Hungarian): see the project statistics of the medium languages at http://www.openthesaurus.org/.
