• Performing a fuzzy search may retrieve terms with similar spellings: (("monographien band i") OR ((("monographien band 38") OR ("monographien der 18"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"monographien band i\") OR (((\"monographien band 38\") OR (\"monographien der 18\"))))*".
• Removing quotes may allow a broader search: (( monographien band i ) OR ((( monographien band 38 ) OR ( monographien der 18 ))))*.
