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