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