• Performing a fuzzy search may retrieve terms with similar spellings: "((werner von) OR (werkes von)) siemens (((ingoe" OR ginge") OR (rggingoee" OR ingoee")) OR ing")~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((werner von) OR (werkes von)) siemens (((ingoe\" OR ginge\") OR (rggingoee\" OR ingoee\")) OR ing\")*".
• Removing quotes may allow a broader search: ((werner von) OR (werkes von)) siemens (((ingoe OR ginge ) OR (rggingoee OR ingoee )) OR ing )*.
