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