Perhaps you should try some spelling variations:
multiling » multilingue, multilingues
multilingueues » multilingueueues, multilinguesueues, multilingues, multilingue, multiligues
{uml}uismo." » {uml}mismo.", {uml}sismo.", {uml}iismo.", {uml}umismo.", {uml}usismo.", {uml}uiso."
{uml}umismo." » {uml}ummismo.", {uml}umsismo.", {uml}umiso."
{uml}ismo." » {uml}mismo.", {uml}sismo.", {uml}iso."

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: "(multiling or multilingueues)(({uml}uismo." or {uml}umismo.") or ({uml}ismo." OR {uml}istmo."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: "(multiling OR multilingueues)(({uml}uismo." or {uml}umismo.") OR ({uml}ismo." OR {uml}istmo.")).
• Removing quotes may allow a broader search: (multiling or multilingueues)(({uml}uismo. or {uml}umismo. ) or ({uml}ismo. OR {uml}istmo. )).
• Adding a wildcard symbol may retrieve word variants: "(multiling or multilingueues)(({uml}uismo." or {uml}umismo.") or ({uml}ismo." OR {uml}istmo."))*.
