• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu xanh - ((hanh trang) OR (hanh trinh)) cua phuong dong ((tac toan) OR (hach toan)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - ((hanh trang) or (hanh trinh)) cua phuong dong ((tac toan) OR (hach toan)) ban~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - ((hanh trang) or (hanh trinh)) cua phuong dong ((tac toan) OR (hach toan)) ban*.
