Perhaps you should try some spelling variations:
"libre{acute}dias." » "libro{acute}dias.", "libre{acute}dios."
"libre{acute}diaz." » "libro{acute}diaz."
"llibre{acute}vial." » "llibro{acute}vial.", "llibre{acute}vidal."
"librer{acute}via." » "libror{acute}via.", "librero{acute}via.", "llibrer{acute}via.", "libres{acute}via."

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((("libre{acute}dias." OR "libre{acute}diaz.") or "llibre{acute}vial.") or "librer{acute}via.")~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((("libre{acute}dias." OR "libre{acute}diaz.") OR "llibre{acute}vial.") OR "librer{acute}via.").
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((\"libre{acute}dias.\" OR \"libre{acute}diaz.\") or \"llibre{acute}vial.\") or \"librer{acute}via.\")".
• Removing quotes may allow a broader search: ((( libre{acute}dias. OR libre{acute}diaz. ) or llibre{acute}vial. ) or librer{acute}via. ).
• Adding a wildcard symbol may retrieve word variants: ((("libre{acute}dias." OR "libre{acute}diaz.") or "llibre{acute}vial.") or "librer{acute}via.")*.
