• Performing a fuzzy search may retrieve terms with similar spellings: (((("hinrich hinz") OR ((("hsinrich hsinz") OR ("zheinrich hsinz"))))) OR ("heinrich hein"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"hinrich hinz\") OR (((\"hsinrich hsinz\") OR (\"zheinrich hsinz\"))))) OR (\"heinrich hein\"))".
• Removing quotes may allow a broader search: (((( hinrich hinz ) OR ((( hsinrich hsinz ) OR ( zheinrich hsinz ))))) OR ( heinrich hein )).
• Adding a wildcard symbol may retrieve word variants: (((("hinrich hinz") OR ((("hsinrich hsinz") OR ("zheinrich hsinz"))))) OR ("heinrich hein"))*.
