• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - ((hanh tang) OR (thanh trung)) cua nhung cong ((manh toan) OR (anh tuan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - ((hanh tang) or (thanh trung)) cua nhung cong ((manh toan) OR (anh tuan)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - ((hanh tang) or (thanh trung)) cua nhung cong ((manh toan) OR (anh tuan)) cau*.
