Perhaps you should try some spelling variations:
vulgarie » vulgarise, vulgaris, vulgare
vulgarische » bulgarische, bulgarischen, bulgarischer
bulgarian » bulgaria, hungarian, vulgarian, bulgerian, bulgariaian
vulgaria » bulgaria, vulgaris, vulgari
bulgar » vulgar, bulger, bulgaria
bulgare » vulgare, bulgere, bulgariae, bulgarie, bulgarien

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((vulgarie OR (vulgarische OR (bulgarian OR vulgaria))) OR (((bulgar OR bulgare) OR vulgarie) OR bulge))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vulgarie or (vulgarische or (bulgarian or vulgaria))) or (((bulgar OR bulgare) or vulgarie) or bulge))*".
