• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho hieu) OR (ho chieu)) lang - thanh truong tham nhung cong van ((toan cao) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho hieu) OR (ho chieu)) lang - thanh truong tham nhung cong van ((toan cao) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: ((ho hieu) OR (ho chieu)) lang - thanh truong tham nhung cong van ((toan cao) or (toan tap))*.
