• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((said corporation) or (_ corporation)) ((biography series) OR (biography pericles)) ) or ( road ((corporation biography) or (complete bibliography)) series ))".
• Adding a wildcard symbol may retrieve word variants: (( ((said corporation) or (_ corporation)) ((biography series) OR (biography pericles)) ) or ( road ((corporation biography) or (complete bibliography)) series ))*.
