Perhaps you should try some spelling variations:
bulgariae » bulgaria, bulgarian, bulgarie
vulgareiae » vulgarise
bulgaricae » bulgarische, bulgaria, bulgarian, bulgariae, bulgariane
bulgarica » bulgaria, bulgarisch, bulgarian

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