• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) OR (chieu xanh)) - hanh tang cua nhung ((cong dan) OR (cong tan)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) OR (chieu xanh)) - hanh tang cua nhung ((cong dan) OR (cong tan)) toan ban*.
