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