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