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