Perhaps you should try some spelling variations:
bulgariae » bulgaria, bulgarian, bulgarians
bulgarie » bulgarien, bulgaria, bulgarian
bulgaricae » bulgarische, bulgaria, bulgarian, bulgariae, bulgariane
bulgarica » bulgaria, bulgarisch, bulgarian
bulger » bulge, bulges

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