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