• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - thanh ((tung va) OR (trung va)) nhung ((duong van) OR (dang van)) tan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - thanh ((tung va) or (trung va)) nhung ((duong van) OR (dang van)) tan cau".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - thanh ((tung va) or (trung va)) nhung ((duong van) OR (dang van)) tan cau*.
