• The words AND, OR and NOT may confuse the search; try adding quotes: "((african national) or (american national)) road ((((rail championships) OR (rally championship))) or (iv championship))".
• Adding a wildcard symbol may retrieve word variants: ((african national) or (american national)) road ((((rail championships) OR (rally championship))) or (iv championship))*.
