• Performing a fuzzy search may retrieve terms with similar spellings: (( su sach ((ca ve) OR (ca va)) giao thong thong tin ) or ( so sanh che hien gioi co thong minh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( su sach ((ca ve) OR (ca va)) giao thong thong tin ) OR ( so sanh che hien gioi co thong minh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su sach ((ca ve) OR (ca va)) giao thong thong tin ) or ( so sanh che hien gioi co thong minh ))".
• Adding a wildcard symbol may retrieve word variants: (( su sach ((ca ve) OR (ca va)) giao thong thong tin ) or ( so sanh che hien gioi co thong minh ))*.
