Perhaps you should try some spelling variations:
simon davies » simon david, wilson davies, don davies
cohen simon » cohen timo, holden simon, cohen setton
simon dawes » simon dale, simon das, simon mawer's
ian davies » jane davies, fanny davies

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: (( nolen ((simon davies) OR (ian davies)) ) OR ( cohen simon dawes )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( nolen ((simon davies) OR (ian davies)) ) or ( cohen simon dawes ))".
• Adding a wildcard symbol may retrieve word variants: (( nolen ((simon davies) OR (ian davies)) ) or ( cohen simon dawes ))*.
