Perhaps you should try some spelling variations:
bulgariae » bulgaricae, bulgarian, bulgarie
bulgareiia » bulgariia, bulgarica
bulgareie » bulgarie, bulgarien, bulgare
vulgare » vulgaris, vulgarly
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: (((bulgariae OR bulgaria) OR bulgareiia) OR ((vulgar OR (bulgareie OR vulgare)) OR bulges)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((bulgariae OR bulgaria) or bulgareiia) or ((vulgar or (bulgareie or vulgare)) or bulges))".
• Adding a wildcard symbol may retrieve word variants: (((bulgariae OR bulgaria) or bulgareiia) or ((vulgar or (bulgareie or vulgare)) or bulges))*.
