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

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