• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach che ((ve giai) OR (ve giao)) con dong kinh ) OR ( tu sach ha me gioi bon phong tin )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach che ((ve giai) OR (ve giao)) con dong kinh ) or ( tu sach ha me gioi bon phong tin ))".
