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