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

Try widening your search to All Fields.

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