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