• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"frank kuh\") OR (\"frank kuhk\"))) OR (((\"frank kuch\") OR (\"frank kuche\"))))) OR (\"franz kuh\"))".
• Removing quotes may allow a broader search: (((((( frank kuh ) OR ( frank kuhk ))) OR ((( frank kuch ) OR ( frank kuche ))))) OR ( franz kuh )).
• Adding a wildcard symbol may retrieve word variants: (((((("frank kuh") OR ("frank kuhk"))) OR ((("frank kuch") OR ("frank kuche"))))) OR ("franz kuh"))*.
