Perhaps you should try some spelling variations:
vulgari » vulgaris, vulgare, bulgaria
bulgeriae » bulgariae, bulgaricae, bulgaria, bulgeiae, bulgesiae
bulgar » bulgare, bulgaria, bulgarie
bulger » bulge, bulges
bulgere » bulgee, bulgese, bulgare, bilgere, burgere

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