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