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