Perhaps you should try some spelling variations:
vulgariae » bulgariae, vulgarise, bulgaricae, vulgarie, vulvariae
vulgaria » vulgaris, vulgari, vulvaria
bulgaria » vulgaria, bulgarieia
bulgar » vulgar, bulgarie
bulgare » vulgare, bulgariee, bulgarie, bulgarien
vulgarien » bulgarien, bulgariens, vulgarisee
bulger » bulges

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: ((vulgariae OR (bulgaria OR vulgaria)) OR (((bulgar OR vulgarien) OR bulgare) OR (bulger OR bulge)))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vulgariae or (bulgaria OR vulgaria)) or (((bulgar or vulgarien) or bulgare) or (bulger or bulge)))*".
