• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - ((hanh tinh) OR (thanh tinh)) cua nhung ((hong van) OR (phong van)) tuan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((hanh tinh) or (thanh tinh)) cua nhung ((hong van) OR (phong van)) tuan ban~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((hanh tinh) or (thanh tinh)) cua nhung ((hong van) OR (phong van)) tuan ban*.
