• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ian dr johnson\") or (\"ian dean johnson\"))) or (((\"ian les johnson\") OR (\"ian glen johnson\"))))".
• Removing quotes may allow a broader search: (((( ian dr johnson ) or ( ian dean johnson ))) or ((( ian les johnson ) OR ( ian glen johnson )))).
• Adding a wildcard symbol may retrieve word variants: (((("ian dr johnson") or ("ian dean johnson"))) or ((("ian les johnson") OR ("ian glen johnson"))))*.
