• If you are trying to use Boolean operators, they must be ALL CAPS: (( (phung OR phuong) thi que van. hoc dung quoc lo ) OR ( nhung loi quan va. hoc dan quoc mo ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( (phung OR phuong) thi que van. hoc dung quoc lo ) or ( nhung loi quan va. hoc dan quoc mo ))*".
