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