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