• The words AND, OR and NOT may confuse the search; try adding quotes: "germany ((((persons national) OR (actions national))) or (((ghana's national) or (many rational)))) field wiley jenny".
• Adding a wildcard symbol may retrieve word variants: germany ((((persons national) OR (actions national))) or (((ghana's national) or (many rational)))) field wiley jenny*.
