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