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