• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sang - ((hanh ban) OR (thanh ban)) cua nhung ((cuong bang) OR (dong bang)) phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sang - ((hanh ban) OR (thanh ban)) cua nhung ((cuong bang) or (dong bang)) phan cau~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sang - ((hanh ban) OR (thanh ban)) cua nhung ((cuong bang) or (dong bang)) phan cau*.
