• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ corporation biography series") OR ("_ corporation biography pericles"))) OR ("a corporation biography series"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"_ corporation biography series\") OR (\"_ corporation biography pericles\"))) or (\"a corporation biography series\"))*".
• Removing quotes may allow a broader search: (((( _ corporation biography series ) OR ( _ corporation biography pericles ))) or ( a corporation biography series ))*.
