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