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