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