• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"ingenieurwissenschaftliche bibliothek engineering select library\") OR (\"ingenieurwissenschaftliche methodik engineering select library\"))".
• Removing quotes may allow a broader search: (( ingenieurwissenschaftliche bibliothek engineering select library ) OR ( ingenieurwissenschaftliche methodik engineering select library )).
• Adding a wildcard symbol may retrieve word variants: (("ingenieurwissenschaftliche bibliothek engineering select library") OR ("ingenieurwissenschaftliche methodik engineering select library"))*.
