• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach che ((me gioi) OR (me giai)) can hong minh ) OR ( tu sach cha ve gioi can khong minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach che ((me gioi) OR (me giai)) can hong minh ) or ( tu sach cha ve gioi can khong minh ))".
