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