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