• Performing a fuzzy search may retrieve terms with similar spellings: "((werner von) OR (werkes von)) siemens ((((ringe" OR rging") OR ringeo") 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 rging\") OR ringeo\") OR lginge\") OR ing\")*".
• Removing quotes may allow a broader search: ((werner von) OR (werkes von)) siemens ((((ringe OR rging ) OR ringeo ) OR lginge ) OR ing )*.
