• Performing a fuzzy search may retrieve terms with similar spellings: (( ((vu sach) OR (vu khach)) che do giai cong khong tin ) or ( tu sach cha me gioi co phong tien ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((vu sach) OR (vu khach)) che do giai cong khong tin ) OR ( tu sach cha me gioi co phong tien )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((vu sach) OR (vu khach)) che do giai cong khong tin ) or ( tu sach cha me gioi co phong tien ))".
• Adding a wildcard symbol may retrieve word variants: (( ((vu sach) OR (vu khach)) che do giai cong khong tin ) or ( tu sach cha me gioi co phong tien ))*.
