Perhaps you should try some spelling variations:
vulgariae » bulgariae, vulgarise, vulgaridad
bulgaricae » bulgarica, bulgarische, bulgaria, bulgareicae, vulgaricae, bulgariaicae
bulgarian » bulgaria, hungarian, bulgareian, vulgarian, bulgariaian
bulgar » bulgare, vulgar, bulgaria
bulgarien » bulgareien, vulgarien, bulgariaien, bulgaria

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 bulgarian) OR (((bulgar OR bulgarien) OR (bulger OR bulge)) OR bulges))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((vulgariae OR bulgaricae) or bulgarian) or (((bulgar or bulgarien) or (bulger or bulge)) or bulges))*".
