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