• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chu) OR (doi chieu)) sang - thanh trung ((cua phan) OR (cua nhan)) cong tan than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chu) or (doi chieu)) sang - thanh trung ((cua phan) OR (cua nhan)) cong tan than cap~".
• Adding a wildcard symbol may retrieve word variants: ((theo chu) or (doi chieu)) sang - thanh trung ((cua phan) OR (cua nhan)) cong tan than cap*.
