• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"monographien band 18\") OR (((\"monographie von 78\") OR (\"monographie von 1786\"))))~".
• Removing quotes may allow a broader search: (( monographien band 18 ) OR ((( monographie von 78 ) OR ( monographie von 1786 ))))~.
• Adding a wildcard symbol may retrieve word variants: (("monographien band 18") OR ((("monographie von 78") OR ("monographie von 1786"))))*.
