Perhaps you should try some spelling variations:
league basketball » league baseball, male basketball
game basketball » gym basketball, male basketball, based basketball
female leaders » female leadership, female offenders
file leaders » five leaders, fide leaders, file headers
game some » games some, game game, home some

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

• If you are trying to use Boolean operators, they must be ALL CAPS: list of major ((league basketball) OR (game basketball)) game some ((file leaders) OR (female leaders)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "list of major ((league basketball) OR (game basketball)) game some ((file leaders) or (female leaders))".
• Adding a wildcard symbol may retrieve word variants: list of major ((league basketball) OR (game basketball)) game some ((file leaders) or (female leaders))*.
