Perhaps you should try some spelling variations:
vulgarie » vulgarise, vulgaris, vulgare
bulgarische » bulgarischen, ungarische, bulgareische, vulgarische, bulgerische
bulgarian » bulgaria, hungarian, bulgareian, vulgarian, bulgerian
bulgerian » bulgarians, bulgaria, eulerian
vulgaria » bulgaria, vulgaris, vulgari
bulgar » bulgare, vulgar, bulger
bulgarie » bulgareie, vulgarie, bulgerie, 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 bulgerian) OR vulgaria))) OR ((bulgar OR bulgarie) OR bulge))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vulgarie or (bulgarische or ((bulgarian OR bulgerian) or vulgaria))) or ((bulgar or bulgarie) or bulge))*".
