• If you are trying to use Boolean operators, they must be ALL CAPS: gia linh hieu luat ((kinh cho) OR (tinh cho)) nguoi viet nhat ((huong tieng) OR (phuong tien)) han*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "gia linh hieu luat ((kinh cho) or (tinh cho)) nguoi viet nhat ((huong tieng) OR (phuong tien)) han*".
