• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"care hermann pethe\") OR (((\"careo hermann pethe\") OR (\"caseo hermann pethe\"))))~".
• Removing quotes may allow a broader search: (( care hermann pethe ) OR ((( careo hermann pethe ) OR ( caseo hermann pethe ))))~.
• Adding a wildcard symbol may retrieve word variants: (("care hermann pethe") OR ((("careo hermann pethe") OR ("caseo hermann pethe"))))*.
