• Performing a fuzzy search may retrieve terms with similar spellings: "((werner von) OR (weiber von)) siemens (((lginge" OR (lingee" OR ringeeee")) OR rging") OR ing")~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((werner von) OR (weiber von)) siemens (((lginge\" OR (lingee\" OR ringeeee\")) OR rging\") OR ing\")".
• Removing quotes may allow a broader search: ((werner von) OR (weiber von)) siemens (((lginge OR (lingee OR ringeeee )) OR rging ) OR ing ).
• Adding a wildcard symbol may retrieve word variants: "((werner von) OR (weiber von)) siemens (((lginge" OR (lingee" OR ringeeee")) OR rging") OR ing")*.
