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