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