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