Perhaps you should try some spelling variations:
vulgarie » vulgarise, vulgaris, vulgare
bulgarische » bulgarischen, ungarische, bulgareische, bulgerische, bulgariaische
bulgarian » bulgaria, hungarian, bulgareian, bulgerian, bulgariaian
vulgaria » bulgaria, vulgaris, vulgari
bulgar » bulgare, bulger, bulgaria
bulgarie » bulgareie, bulgerie, bulgariaie, bulgarien, bulgaria, vulgaris

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 (bulgarische OR (bulgarian OR vulgaria))) OR (((bulgar OR vulgar) OR bulgarie) OR bulge))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vulgarie or (bulgarische or (bulgarian or vulgaria))) or (((bulgar OR vulgar) or bulgarie) or bulge))*".
