• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach che my gioi cam hoang minh ) OR ( tu sach ((bai ve) OR (ban ve)) gioi co thong minh ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach che my gioi cam hoang minh ) or ( tu sach ((bai ve) OR (ban ve)) gioi co thong minh ))*".
