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