• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"librer{acute}vias.\" OR \"librero{acute}ias.\") OR (\"librer{acute}dias.\" OR \"librer{acute}diaz.\"))".

• Adding a wildcard symbol may retrieve word variants: (("librer{acute}vias." OR "librero{acute}ias.") OR ("librer{acute}dias." OR "librer{acute}diaz."))*.
