Perhaps you should try some spelling variations:
brian larkin » brian lambkin, ian larkin, brian perkins
brian clark » brown clark, brian black, burton clark
ian clark » iain clark, ewan clark, a clark
rugby » ruby, rigby

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: ((((ian clark) OR (brian clark))) OR (brian larkin)) (rugby union).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((ian clark) OR (brian clark))) or (brian larkin)) (rugby union)".
• Adding a wildcard symbol may retrieve word variants: ((((ian clark) OR (brian clark))) or (brian larkin)) (rugby union)*.
