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