Perhaps you should try some spelling variations:
multiling » multilingue, multilingues
multilingueues » multilingueueues, multilinguesueues, multilingues, multilingue, multiligues
{uml}uismo." » {uml}sismo.", {uml}iismo.", {uml}uisme.", {uml}usismo.", {uml}uistmo.", {uml}uiso."
{uml}mismo." » {uml}msismo.", {uml}mistmo.", {uml}miso."
{uml}ismo." » {uml}sismo.", {uml}istmo.", {uml}iso."

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

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