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