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