• If you are trying to use Boolean operators, they must be ALL CAPS: (((("lecture notes of the tra matematica italian") OR ("lecture notes of the la matematica italian"))) OR ("lecture notes of the unione mathematical vitality")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"lecture notes of the tra matematica italian\") OR (\"lecture notes of the la matematica italian\"))) or (\"lecture notes of the unione mathematical vitality\"))".
• Removing quotes may allow a broader search: (((( lecture notes of the tra matematica italian ) OR ( lecture notes of the la matematica italian ))) or ( lecture notes of the unione mathematical vitality )).
• Adding a wildcard symbol may retrieve word variants: (((("lecture notes of the tra matematica italian") OR ("lecture notes of the la matematica italian"))) or ("lecture notes of the unione mathematical vitality"))*.
