• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc thieu)) sang - thanh thang cua trung ((cong tap) OR (cong tan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) sang - thanh thang cua trung ((cong tap) OR (cong tan)) toan cau*.
