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