Perhaps you should try some spelling variations:
vulgariae » bulgariae, vulgarise, vulgaridad
bulgariia » bulgarica, bulgarian, bulgarie
bulgaricae » bulgarica, bulgarische, bulgarian
bulger » bulge
bulgarien » bulgarian
vulgaris » vulgar
bulges » bulge

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 (bulgariia OR bulgaricae)) OR (((bulgaria OR bulger) OR (bulgarien OR vulgaris)) OR bulges))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vulgariae or (bulgariia OR bulgaricae)) or (((bulgaria or bulger) or (bulgarien or vulgaris)) or bulges))*".
