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