• The words AND, OR and NOT may confuse the search; try adding quotes: "bibliothek ((historical OR historica) OR istoria) ((roumanian OR roumania) OR romania) 1~".
• Adding a wildcard symbol may retrieve word variants: bibliothek ((historical OR historica) OR istoria) ((roumanian OR roumania) OR romania) 1*.
