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