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