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