• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((werner von) OR (werkes von)) siemens ((ringe\" OR ringeoo\") OR ((fingeo\" OR finge\") OR inge\"))".
• Removing quotes may allow a broader search: ((werner von) OR (werkes von)) siemens ((ringe OR ringeoo ) OR ((fingeo OR finge ) OR inge )).
• Adding a wildcard symbol may retrieve word variants: "((werner von) OR (werkes von)) siemens ((ringe" OR ringeoo") OR ((fingeo" OR finge") OR inge"))*.
