Perhaps you should try some spelling variations:
multiling » multilingue
multilingues » multilingueues, multilingue, multilinguismo
{uml}miso." » {uml}mismo.", {uml}misio.", {uml}mito."
{uml}omiso." » {uml}omismo.", {uml}omisio.", {uml}omito.", {uml}comiso."
{uml}omito." » {uml}komito.", {uml}vomito.", {uml}mito."
{uml}ismo." » {uml}mismo.", {uml}sismo.", {uml}istmo."

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}miso." or ({uml}omiso." OR {uml}omito.")) or {uml}ismo.")~.
• If you are trying to use Boolean operators, they must be ALL CAPS: "(multiling OR multilingues)(({uml}miso." or ({uml}omiso." OR {uml}omito.")) or {uml}ismo.").
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(multiling or multilingues)(({uml}miso.\" or ({uml}omiso.\" OR {uml}omito.\")) or {uml}ismo.\")".
• Removing quotes may allow a broader search: (multiling or multilingues)(({uml}miso. or ({uml}omiso. OR {uml}omito. )) or {uml}ismo. ).
• Adding a wildcard symbol may retrieve word variants: "(multiling or multilingues)(({uml}miso." or ({uml}omiso." OR {uml}omito.")) or {uml}ismo.")*.
