• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) or (ho chieu)) xanh - canh tranh cua nhung ((cong ngang) OR (cong nhan)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) or (ho chieu)) xanh - canh tranh cua nhung ((cong ngang) OR (cong nhan)) toan ban*.
