• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho hieu) OR (hoi hieu)) lang - thanh tung cua nhung ((cong ban) OR (cong san)) hang cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho hieu) or (hoi hieu)) lang - thanh tung cua nhung ((cong ban) OR (cong san)) hang cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho hieu) or (hoi hieu)) lang - thanh tung cua nhung ((cong ban) OR (cong san)) hang cau*.
