Perhaps you should try some spelling variations:
multiling » multilingues
multilingue » multilinguesue
multilingueuismo » multilinguesueuismo, multilinguismo, multilingualism, multilinguisme, multilingueumismo, multilingueusismo, multilingueuistmo
{uml}usmismo." » {uml}asimismo.", {uml}usmmismo.", {uml}usmsismo.", {uml}usmistmo."
{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 multilingue) or multilingueuismo)({uml}usmismo." or {uml}ismo.")~.
• If you are trying to use Boolean operators, they must be ALL CAPS: "((multiling OR multilingue) OR multilingueuismo)({uml}usmismo." or {uml}ismo.").
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((multiling OR multilingue) or multilingueuismo)({uml}usmismo.\" or {uml}ismo.\")".
• Removing quotes may allow a broader search: ((multiling OR multilingue) or multilingueuismo)({uml}usmismo. or {uml}ismo. ).
• Adding a wildcard symbol may retrieve word variants: "((multiling OR multilingue) or multilingueuismo)({uml}usmismo." or {uml}ismo.")*.
