• If you are trying to use Boolean operators, they must be ALL CAPS: (((("michael kirby author") OR ("michael kirby anthony"))) OR ((("michael della author") OR ("michael cells author"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"michael kirby author\") or (\"michael kirby anthony\"))) or (((\"michael della author\") OR (\"michael cells author\"))))*".
• Removing quotes may allow a broader search: (((( michael kirby author ) or ( michael kirby anthony ))) or ((( michael della author ) OR ( michael cells author ))))*.
