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