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