• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho hieu) OR (nho hieu)) lang - thanh thong cap thong cong ((manh toan) OR (anh tuan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho hieu) OR (nho hieu)) lang - thanh thong cap thong cong ((manh toan) or (anh tuan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho hieu) OR (nho hieu)) lang - thanh thong cap thong cong ((manh toan) or (anh tuan)) cau*.
