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