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