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