• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach che ve gioi van ((dong tin) OR (thong tin)) ) OR ( thu sach nha mo gioi bon hong tin ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach che ve gioi van ((dong tin) OR (thong tin)) ) or ( thu sach nha mo gioi bon hong tin ))*".
