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