Perhaps you should try some spelling variations:
bulgariia » bulgaria, bulgarian, bulgarien
bulgarica » bulgaria, bulgarisch, bulgarian
bulgaricae » bulgariae, bulgarische, bulgariane, bulgaria, bulgarian
bulger » bulges
vulgare » vulgaris, vulgarly

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: (((bulgariia OR bulgarica) OR bulgaricae) OR ((vulgar OR (bulger OR bulge)) OR vulgare)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((bulgariia OR bulgarica) or bulgaricae) or ((vulgar or (bulger or bulge)) or vulgare))".
• Adding a wildcard symbol may retrieve word variants: (((bulgariia OR bulgarica) or bulgaricae) or ((vulgar or (bulger or bulge)) or vulgare))*.
