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