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