• Performing a fuzzy search may retrieve terms with similar spellings: "((werner von) OR (werkes von)) siemens ((ring" OR rgginge") OR ((gginge" 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 rgginge\") OR ((gginge\" OR gingoe\") OR ing\"))".
• Removing quotes may allow a broader search: ((werner von) OR (werkes von)) siemens ((ring OR rgginge ) OR ((gginge OR gingoe ) OR ing )).
• Adding a wildcard symbol may retrieve word variants: "((werner von) OR (werkes von)) siemens ((ring" OR rgginge") OR ((gginge" OR gingoe") OR ing"))*.
