• The words AND, OR and NOT may confuse the search; try adding quotes: "((sicho OR (fsicher OR (isich OR (ficho OR (iiischtn OR schon))))) OR (isch OR sch))~".
• Adding a wildcard symbol may retrieve word variants: ((sicho OR (fsicher OR (isich OR (ficho OR (iiischtn OR schon))))) OR (isch OR sch))*.
