• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - thanh doan ((tuan nhung) OR (quan nhung)) cong ((tac toan) OR (tap toan)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - thanh doan ((tuan nhung) OR (quan nhung)) cong ((tac toan) or (tap toan)) ban~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - thanh doan ((tuan nhung) OR (quan nhung)) cong ((tac toan) or (tap toan)) ban*.
