chua dung » chua dong, thuat dung, chua nhung
dung cong » dung trong
ho chieu » theo chieu, hoc thieu, doi chieu

• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho hieu) OR (ho chieu)) lang - nhan dang chua dung cong ((dan toan) OR (van toan)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho hieu) or (ho chieu)) lang - nhan dang chua dung cong ((dan toan) OR (van toan)) tap~".
• Adding a wildcard symbol may retrieve word variants: ((ho hieu) or (ho chieu)) lang - nhan dang chua dung cong ((dan toan) OR (van toan)) tap*.
