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