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