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