• If you are trying to use Boolean operators, they must be ALL CAPS: (("wien simon davies") OR ((("cohen simon davies") OR ("cohen simon dawes")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"wien simon davies\") or (((\"cohen simon davies\") OR (\"cohen simon dawes\"))))".
• Removing quotes may allow a broader search: (( wien simon davies ) or ((( cohen simon davies ) OR ( cohen simon dawes )))).
• Adding a wildcard symbol may retrieve word variants: (("wien simon davies") or ((("cohen simon davies") OR ("cohen simon dawes"))))*.
