• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach ((ca va) OR (c va)) giao cong thuong minh ) OR ( tu sach cha va gia cong hoan minh ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach ((ca va) OR (c va)) giao cong thuong minh ) or ( tu sach cha va gia cong hoan minh ))*".
