Perhaps you should try some spelling variations:
multiling » multilingue
multilingues » multilingueues, multilingue, multilinguismo
{uml}ismo." » {uml}istmo.", {uml}iso."
{uml}mismo." » {uml}mistmo.", {uml}miso."
{uml}sismo." » {uml}sistmo.", {uml}siso.", {uml}sismos.", {uml}simo."
{uml}miso." » {uml}misio.", {uml}omiso.", {uml}mito."

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}ismo." OR {uml}mismo.") or {uml}sismo.") or {uml}miso.")~.
• If you are trying to use Boolean operators, they must be ALL CAPS: "(multiling OR multilingues)((({uml}ismo." OR {uml}mismo.") OR {uml}sismo.") or {uml}miso.").
• Removing quotes may allow a broader search: (multiling or multilingues)((({uml}ismo. OR {uml}mismo. ) or {uml}sismo. ) or {uml}miso. ).
• Adding a wildcard symbol may retrieve word variants: "(multiling or multilingues)((({uml}ismo." OR {uml}mismo.") or {uml}sismo.") or {uml}miso.")*.
