• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"can deny johnson\") OR (\"can henry johnson\"))) or (\"change des johnson\"))".
• Removing quotes may allow a broader search: (((( can deny johnson ) OR ( can henry johnson ))) or ( change des johnson )).
• Adding a wildcard symbol may retrieve word variants: (((("can deny johnson") OR ("can henry johnson"))) or ("change des johnson"))*.
