Perhaps you should try some spelling variations:
vulgariae » bulgariae, vulgarise, bulgaricae
bulgariaien » bulgarian, bulgarien, bulgariae, vulgariaien, bulgariaiaien
bulgar » vulgar, bulgaria
bulgarie » vulgarie, bulgariaie, bulgarien, bulgaria, bulgarian
bulgare » vulgare, bulgariae, bulgarien, bulgaria
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: ((vulgariae OR bulgariaien) OR (((bulgar OR bulgarie) OR bulgare) OR bulger))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vulgariae or bulgariaien) or (((bulgar OR bulgarie) or bulgare) or bulger))*".
