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