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