"librorum{acute}rio." » "librosrum{acute}rio.", "librorvm{acute}rio."
"librer{acute}dios." » "librero{acute}dios.", "llibrer{acute}dios.", "libre{acute}dios.", "librer{acute}dos.", "librer{acute}rios."
"librer{acute}rio." » "librero{acute}rio.", "llibrer{acute}rio.", "libre{acute}rio."

• If you are trying to use Boolean operators, they must be ALL CAPS: ("libro{acute}ias." OR ("librer{acute}dios." OR ("librer{acute}rio." OR "librorum{acute}rio."))).
• Removing quotes may allow a broader search: ( libro{acute}ias. or ( librer{acute}dios. or ( librer{acute}rio. or librorum{acute}rio. ))).
• Adding a wildcard symbol may retrieve word variants: ("libro{acute}ias." or ("librer{acute}dios." or ("librer{acute}rio." or "librorum{acute}rio.")))*.
