Perhaps you should try some spelling variations:
multiling » multilingues
multilingue » multilinguesue
{uml}uistmo." » {uml}istmo.", {uml}uismo."
{uml}ismo." » {uml}mismo.", {uml}istmo.", {uml}iso."
{uml}sismo." » {uml}smismo.", {uml}sistmo.", {uml}siso.", {uml}sismos.", {uml}mismo.", {uml}simo."
{uml}omiso." » {uml}comiso."

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 multilingue)({uml}uistmo." or (({uml}ismo." OR {uml}omiso.") or {uml}sismo."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(multiling OR multilingue)({uml}uistmo.\" or (({uml}ismo.\" OR {uml}omiso.\") or {uml}sismo.\"))".
• Removing quotes may allow a broader search: (multiling OR multilingue)({uml}uistmo. or (({uml}ismo. OR {uml}omiso. ) or {uml}sismo. )).
• Adding a wildcard symbol may retrieve word variants: "(multiling OR multilingue)({uml}uistmo." or (({uml}ismo." OR {uml}omiso.") or {uml}sismo."))*.
