• If you are trying to use Boolean operators, they must be ALL CAPS: ((bulgariaiae OR (vulgaricae OR bulgariae)) OR ((bulgar OR bulgare) OR bulger))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((bulgariaiae or (vulgaricae OR bulgariae)) or ((bulgar or bulgare) or bulger))*".
