• Performing a fuzzy search may retrieve terms with similar spellings: (( tu cach ((ta me) OR (ca me)) gioi co thong tin ) or ( thuoc sach ha me gioi song khong tinh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu cach ((ta me) OR (ca me)) gioi co thong tin ) OR ( thuoc sach ha me gioi song khong tinh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu cach ((ta me) OR (ca me)) gioi co thong tin ) or ( thuoc sach ha me gioi song khong tinh ))".
• Adding a wildcard symbol may retrieve word variants: (( tu cach ((ta me) OR (ca me)) gioi co thong tin ) or ( thuoc sach ha me gioi song khong tinh ))*.
