• Removing quotes may allow a broader search: (((( hugh griffiths, mrs griffiths ) or ( hugh griffiths, _ griffiths ))) or ( a griffiths, mark griffiths )).
• Adding a wildcard symbol may retrieve word variants: (((("hugh griffiths, mrs griffiths") or ("hugh griffiths, _ griffiths"))) or ("a griffiths, mark griffiths"))*.
