• Performing a fuzzy search may retrieve terms with similar spellings: (("librer{acute}dias." OR "librer{acute}diaz.") OR ("librer{acute}dios." OR "libreso{acute}dios."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"librer{acute}dias.\" OR \"librer{acute}diaz.\") OR (\"librer{acute}dios.\" OR \"libreso{acute}dios.\"))".
• Removing quotes may allow a broader search: (( librer{acute}dias. OR librer{acute}diaz. ) OR ( librer{acute}dios. OR libreso{acute}dios. )).
• Adding a wildcard symbol may retrieve word variants: (("librer{acute}dias." OR "librer{acute}diaz.") OR ("librer{acute}dios." OR "libreso{acute}dios."))*.
