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