Perhaps you should try some spelling variations:
league person » league hero, league jason
person three » persons three, personas three, version three
2008 ieee » 2018 ieee, 2009 ieee
world go » world 1, world 10, world 12
world 11 » world 1, world 10, world 2

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: "2008 ieee ((world go) OR (world 11)) league person three".
• Adding a wildcard symbol may retrieve word variants: 2008 ieee ((world go) OR (world 11)) league person three*.
