• Performing a fuzzy search may retrieve terms with similar spellings: (( su sach dao moi ((gioi con) OR (gioi bon)) dong tin ) or ( tu cac thue me giai han tdong tinh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( su sach dao moi ((gioi con) OR (gioi bon)) dong tin ) OR ( tu cac thue me giai han tdong tinh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su sach dao moi ((gioi con) OR (gioi bon)) dong tin ) or ( tu cac thue me giai han tdong tinh ))".
• Adding a wildcard symbol may retrieve word variants: (( su sach dao moi ((gioi con) OR (gioi bon)) dong tin ) or ( tu cac thue me giai han tdong tinh ))*.
