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