Perhaps you should try some spelling variations:
bulgare » bulgarie, bulgarien, vulgares, vulgare, bulgere, bulgariee
bulgariae » bulgaricae, bulgarian, bulgarie, vulgariae, bulgeriae, bulgarieiae
vulgare » vulgar, vulgaris, vulgarly
bulgaria » vulgaria, bulgeria, bulgarieia
bulgar » vulgar, bulger, bulgarie

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: (((bulgare OR (bulgariae OR bulgaria)) OR vulgare) OR bulgar).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((bulgare or (bulgariae OR bulgaria)) or vulgare) or bulgar)".
• Adding a wildcard symbol may retrieve word variants: (((bulgare or (bulgariae OR bulgaria)) or vulgare) or bulgar)*.
