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