• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"vieweg studium; Grundkurs Mathematik\") OR (\"viewed studium; Grundkurs Mathematik\"))".
• Removing quotes may allow a broader search: (( vieweg studium; Grundkurs Mathematik ) OR ( viewed studium; Grundkurs Mathematik )).
• Adding a wildcard symbol may retrieve word variants: (("vieweg studium; Grundkurs Mathematik") OR ("viewed studium; Grundkurs Mathematik"))*.
