• If you are trying to use Boolean operators, they must be ALL CAPS: (("biblioteca medicea") OR ((("biblioteca americana") OR ("biblioteca ambrosiana")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"biblioteca medicea\") or (((\"biblioteca americana\") OR (\"biblioteca ambrosiana\"))))".
• Removing quotes may allow a broader search: (( biblioteca medicea ) or ((( biblioteca americana ) OR ( biblioteca ambrosiana )))).
• Adding a wildcard symbol may retrieve word variants: (("biblioteca medicea") or ((("biblioteca americana") OR ("biblioteca ambrosiana"))))*.
