• The words AND, OR and NOT may confuse the search; try adding quotes: "bibliothek (istorice OR ((historisch OR historischen) OR historische)) (roumania OR romanian) 1~".
• Adding a wildcard symbol may retrieve word variants: bibliothek (istorice OR ((historisch OR historischen) OR historische)) (roumania OR romanian) 1*.
