• If you are trying to use Boolean operators, they must be ALL CAPS: tu cao ky lang van hieu. ((hieu ve) OR (hieu va)) cam cuc ban thanh hai ((cau trieu) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cao ky lang van hieu. ((hieu ve) OR (hieu va)) cam cuc ban thanh hai ((cau trieu) or (va triet))".
