• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach ((cba me) OR (cha me)) gioi can dong minh ) OR ( tu sach han me gioi can tong minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach ((cba me) OR (cha me)) gioi can dong minh ) or ( tu sach han me gioi can tong minh ))".
• Adding a wildcard symbol may retrieve word variants: (( te sach ((cba me) OR (cha me)) gioi can dong minh ) or ( tu sach han me gioi can tong minh ))*.
