• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc chieu) OR (ho chieu)) xanh - manh ((trung cua) OR (trung thanh)) nhung cong dam cao cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) OR (ho chieu)) xanh - manh ((trung cua) or (trung thanh)) nhung cong dam cao cap~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) OR (ho chieu)) xanh - manh ((trung cua) or (trung thanh)) nhung cong dam cao cap*.
