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