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