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