• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - ((thanh trien) OR (thanh tien)) thuat nang ((luong thanh) OR (luong anh)) thanh san.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((thanh trien) OR (thanh tien)) thuat nang ((luong thanh) or (luong anh)) thanh san".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - ((thanh trien) OR (thanh tien)) thuat nang ((luong thanh) or (luong anh)) thanh san*.
