Perhaps you should try some spelling variations:
book league » wool league, rookie league, robot league
a workers » 5 workers, a worked
_ workers » _ works
a worker » _ worker, a worked, a work
league a » league _
a chung » a chunk, a change, a chunky

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 ((a worker) OR (((a workers) OR (_ workers)))) book league a chung.
• The words AND, OR and NOT may confuse the search; try adding quotes: "2008 ((a worker) or (((a workers) OR (_ workers)))) book league a chung".
• Adding a wildcard symbol may retrieve word variants: 2008 ((a worker) or (((a workers) OR (_ workers)))) book league a chung*.
