Perhaps you should try some spelling variations:
vulgariae » vulgarise, bulgaricae, vulgaridad
bulgariae » bulgaricae, bulgarie, bulgarians
bulgarian » hungarian
bulgarisch » bulgarische, bulgarischen
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 bulgariae) OR ((bulgaria OR bulgarian) OR (vulcanized OR bulgarisch))) OR (vulgar OR bulger)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((vulgariae OR bulgariae) or ((bulgaria or bulgarian) or (vulcanized or bulgarisch))) or (vulgar or bulger))".
• Adding a wildcard symbol may retrieve word variants: (((vulgariae OR bulgariae) or ((bulgaria or bulgarian) or (vulcanized or bulgarisch))) or (vulgar or bulger))*.
