• The words AND, OR and NOT may confuse the search; try adding quotes: "(((ischen OR (ische OR iisiche)) OR (iischeo OR isicheo)) OR ((nicht OR ischo) OR sch))~".
• Adding a wildcard symbol may retrieve word variants: (((ischen OR (ische OR iisiche)) OR (iischeo OR isicheo)) OR ((nicht OR ischo) OR sch))*.
