• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach bao ((de gian) OR (de gia)) con hong minh ) OR ( tu sach dao my gioi van thong tinh ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach bao ((de gian) OR (de gia)) con hong minh ) or ( tu sach dao my gioi van thong tinh ))*".
