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