• If you are trying to use Boolean operators, they must be ALL CAPS: ((vulgareiae OR (vulgaricae OR (bulgarian OR bulgarisch))) OR ((bulgar OR bulger) OR bulge)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vulgareiae or (vulgaricae or (bulgarian or bulgarisch))) or ((bulgar OR bulger) or bulge))".
• Adding a wildcard symbol may retrieve word variants: ((vulgareiae or (vulgaricae or (bulgarian or bulgarisch))) or ((bulgar OR bulger) or bulge))*.
