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