Perhaps you should try some spelling variations:
multiling » multilingues
multilingue » multilinguesue
{uml}uismo." » {uml}sismo.", {uml}iismo.", {uml}uisme.", {uml}usismo.", {uml}uistmo.", {uml}uiso."
{uml}usismo." » {uml}lusismos.", {uml}ussismo.", {uml}usistmo.", {uml}usiso."
{uml}ismo." » {uml}sismo.", {uml}istmo.", {uml}iso."
{uml}mismo." » {uml}msismo.", {uml}mistmo.", {uml}miso."

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