• Performing a fuzzy search may retrieve terms with similar spellings: "((werner von) OR (werkes von)) siemens (((rginge" OR rgginge") OR (ringe" OR linge")) OR inge")~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((werner von) OR (werkes von)) siemens (((rginge\" OR rgginge\") OR (ringe\" OR linge\")) OR inge\")".
• Removing quotes may allow a broader search: ((werner von) OR (werkes von)) siemens (((rginge OR rgginge ) OR (ringe OR linge )) OR inge ).
• Adding a wildcard symbol may retrieve word variants: "((werner von) OR (werkes von)) siemens (((rginge" OR rgginge") OR (ringe" OR linge")) OR inge")*.
