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