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