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