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