• Performing a fuzzy search may retrieve terms with similar spellings: (( tu sach cap ma gioi co hong tin ) or ( tu sach che me ((giai ban) OR (giai san)) thong tienh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach cap ma gioi co hong tin ) OR ( tu sach che me ((giai ban) OR (giai san)) thong tienh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach cap ma gioi co hong tin ) or ( tu sach che me ((giai ban) OR (giai san)) thong tienh ))".
• Adding a wildcard symbol may retrieve word variants: (( tu sach cap ma gioi co hong tin ) or ( tu sach che me ((giai ban) OR (giai san)) thong tienh ))*.
