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