• The words AND, OR and NOT may confuse the search; try adding quotes: "((bulgariae or ((bulgareie OR bulgareeie) or (bulgariaeian or bulgaria))) or (bulgar or bulger))".
• Adding a wildcard symbol may retrieve word variants: ((bulgariae or ((bulgareie OR bulgareeie) or (bulgariaeian or bulgaria))) or (bulgar or bulger))*.
