• Performing a fuzzy search may retrieve terms with similar spellings: (((("koay gregory w") OR ("koh gregory w"))) OR ("ho gregory k"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"koay gregory w\") OR (\"koh gregory w\"))) OR (\"ho gregory k\"))*".
• Removing quotes may allow a broader search: (((( koay gregory w ) OR ( koh gregory w ))) OR ( ho gregory k ))*.
