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