• Performing a fuzzy search may retrieve terms with similar spellings: "((werner von) OR (werkes von)) siemens ((ring" OR rginge") OR ((ginge" OR gingoe") OR ing"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((werner von) OR (werkes von)) siemens ((ring\" OR rginge\") OR ((ginge\" OR gingoe\") OR ing\"))".
• Removing quotes may allow a broader search: ((werner von) OR (werkes von)) siemens ((ring OR rginge ) OR ((ginge OR gingoe ) OR ing )).
• Adding a wildcard symbol may retrieve word variants: "((werner von) OR (werkes von)) siemens ((ring" OR rginge") OR ((ginge" OR gingoe") OR ing"))*.
