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