• Performing a fuzzy search may retrieve terms with similar spellings: "((weiler von) OR (werkes von)) siemens (((ring" OR ringee") OR (rggingoee" OR ringeee")) OR ing")~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((weiler von) OR (werkes von)) siemens (((ring\" OR ringee\") OR (rggingoee\" OR ringeee\")) OR ing\")".
• Removing quotes may allow a broader search: ((weiler von) OR (werkes von)) siemens (((ring OR ringee ) OR (rggingoee OR ringeee )) OR ing ).
• Adding a wildcard symbol may retrieve word variants: "((weiler von) OR (werkes von)) siemens (((ring" OR ringee") OR (rggingoee" OR ringeee")) OR ing")*.
