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