• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach ca ve ((gioi con) OR (gioi co)) hong minh ) OR ( te sach che ve gioi he thong tin ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach ca ve ((gioi con) OR (gioi co)) hong minh ) or ( te sach che ve gioi he thong tin ))*".
