Perhaps you should try some spelling variations:
vulgariae » bulgariae, vulgarise, bulgaricae
bulgariia » bulgaria, bulgaricae, bulgarian, bulgareiia, vulgariia, bulgeriia
bulgarica » bulgaria, bulgarisch, bulgarian, bulgareica, vulgarica, bulgerica
bulgar » bulgare, vulgar, bulger
bulgarien » bulgareien, vulgarien, bulgerien, bulgarian, bulgaria
vulgaris » bulgaria, 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 bulgarica)) OR ((bulgar OR (bulgarien OR vulgaris)) OR bulges))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vulgariae or (bulgariia OR bulgarica)) or ((bulgar or (bulgarien or vulgaris)) or bulges))*".
