• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((reutter von) OR (werkes von)) siemens (((ringo\" OR (ringooo\" OR ingooo\")) OR rgingo\") OR ing\")".
• Removing quotes may allow a broader search: ((reutter von) OR (werkes von)) siemens (((ringo OR (ringooo OR ingooo )) OR rgingo ) OR ing ).
• Adding a wildcard symbol may retrieve word variants: "((reutter von) OR (werkes von)) siemens (((ringo" OR (ringooo" OR ingooo")) OR rgingo") OR ing")*.
