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