Perhaps you should try some spelling variations:
"football at the 1964 summer olympics" » "football at the 1964 summer olympic", "football at the 1974 summer olympics", "football at the 1966 summer olympics", "football at the 1964 summary olympics"
"football at the 1969 summer olympics" » "football at the 1969 summer olympic"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"football at the 1964 summer olympics\") OR (\"football at the 1969 summer olympics\"))".
• Removing quotes may allow a broader search: (( football at the 1964 summer olympics ) OR ( football at the 1969 summer olympics )).
• Adding a wildcard symbol may retrieve word variants: (("football at the 1964 summer olympics") OR ("football at the 1969 summer olympics"))*.
