• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chi minh) OR (chu van)) - ganh nang quan dung ((cong dan) OR (cong san)) toan cao".
• Adding a wildcard symbol may retrieve word variants: theo ((chi minh) OR (chu van)) - ganh nang quan dung ((cong dan) OR (cong san)) toan cao*.
