• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"monographien band 38\") OR (\"monographien band 1\"))) OR (\"monographien der 33\"))~".
• Removing quotes may allow a broader search: (((( monographien band 38 ) OR ( monographien band 1 ))) OR ( monographien der 33 ))~.
• Adding a wildcard symbol may retrieve word variants: (((("monographien band 38") OR ("monographien band 1"))) OR ("monographien der 33"))*.
