Perhaps you should try some spelling variations:
world papers » world power, world peter
2008 class » 2008 crash, 2008 clara
2008 las » 2008 a, 2008 a2, 2008 a1
a judge » _ judge
judge i » judge a, judge p, judge fit

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: (( 2008 las ((world papers) OR (world part)) a judge _ ) OR ( 2008 class ((world papers) OR (world part)) a judge i )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( 2008 las ((world papers) OR (world part)) a judge _ ) or ( 2008 class ((world papers) OR (world part)) a judge i ))".
• Adding a wildcard symbol may retrieve word variants: (( 2008 las ((world papers) OR (world part)) a judge _ ) or ( 2008 class ((world papers) OR (world part)) a judge i ))*.
