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

Try widening your search to All Fields.

• 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}mismos.")).
• Removing quotes may allow a broader search: (multiling or multilingues)({uml}uismo. or (({uml}sismo. or {uml}simo. ) or {uml}mismos. )).
• Adding a wildcard symbol may retrieve word variants: "(multiling or multilingues)({uml}uismo." or (({uml}sismo." or {uml}simo.") or {uml}mismos."))*.
