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