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