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