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