• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky lang ha hoi. hieu ((van cac) OR (van cau)) toc va doanh ban ((cua tu) OR (cua tuc))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky lang ha hoi. hieu ((van cac) or (van cau)) toc va doanh ban ((cua tu) OR (cua tuc))~".
• Adding a wildcard symbol may retrieve word variants: te sach ky lang ha hoi. hieu ((van cac) or (van cau)) toc va doanh ban ((cua tu) OR (cua tuc))*.
