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