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