• Performing a fuzzy search may retrieve terms with similar spellings: "((werner von) OR (werkes von)) siemens ((ring" OR ringe") OR ((fingo" OR ingo") OR ing"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((werner von) OR (werkes von)) siemens ((ring\" OR ringe\") OR ((fingo\" OR ingo\") OR ing\"))*".
• Removing quotes may allow a broader search: ((werner von) OR (werkes von)) siemens ((ring OR ringe ) OR ((fingo OR ingo ) OR ing ))*.
