• The words AND, OR and NOT may confuse the search; try adding quotes: "(( lecture notes of the sfide matematica della ) or ( lecture notes of the un ((matematici della) OR (matematici per)) ))".
• Adding a wildcard symbol may retrieve word variants: (( lecture notes of the sfide matematica della ) or ( lecture notes of the un ((matematici della) OR (matematici per)) ))*.
