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