Perhaps you should try some spelling variations:
multiling » multilingue
multilingues » multilingueues, multilingue, multilinguismo
{uml}uismo." » {uml}mismo.", {uml}ismo.", {uml}iismo."
{uml}usme." » {uml}use."
{uml}sismo." » {uml}sismos.", {uml}mismo.", {uml}simo."
{uml}siso." » {uml}sieso.", {uml}sido.", {uml}sino."

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