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