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