Perhaps you should try some spelling variations:
multiling » multilingue
multilingues » multilingueues, multilingue, multilinguismo
{uml}sismo. » {uml}sismos., {uml}mismo., {uml}simo., {uml}smismo., {uml}sistmo., {uml}siso.
{uml}umismo. » {uml}ummismo., {uml}umistmo., {uml}umiso.
{uml}ummismo. » {uml}ummmismo., {uml}ummistmo., {uml}ummiso.
{uml}ismo. » {uml}mismo., {uml}istmo., {uml}iso.

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 multilingues)((({uml}umismo. OR {uml}ummismo.) or {uml}sismo.) or {uml}ismo.)~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (multiling OR multilingues)((({uml}umismo. OR {uml}ummismo.) OR {uml}sismo.) OR {uml}ismo.).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(multiling or multilingues)((({uml}umismo. OR {uml}ummismo.) or {uml}sismo.) or {uml}ismo.)".
• Adding a wildcard symbol may retrieve word variants: (multiling or multilingues)((({uml}umismo. OR {uml}ummismo.) or {uml}sismo.) or {uml}ismo.)*.
