• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((weber von) OR (werkes von)) siemens (((ringo\" OR ringoeo\") OR (rggingo\" OR rgingoo\")) OR ing\")~".
• Removing quotes may allow a broader search: ((weber von) OR (werkes von)) siemens (((ringo OR ringoeo ) OR (rggingo OR rgingoo )) OR ing )~.
• Adding a wildcard symbol may retrieve word variants: "((weber von) OR (werkes von)) siemens (((ringo" OR ringoeo") OR (rggingo" OR rgingoo")) OR ing")*.
