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