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