• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"fabel seiler\") OR (\"faber seiler\"))) OR (((\"abel seiner\") OR (\"abel einer\"))))~".
• Removing quotes may allow a broader search: (((( fabel seiler ) OR ( faber seiler ))) OR ((( abel seiner ) OR ( abel einer ))))~.
• Adding a wildcard symbol may retrieve word variants: (((("fabel seiler") OR ("faber seiler"))) OR ((("abel seiner") OR ("abel einer"))))*.
