Perhaps you should try some spelling variations:
multiling » multilingue
multilingues » multilingueues, multilingue, multilinguismo
multilingueues » multilingueueues, multilingue
multiligues » multilingue, multilingual, multipliquen
{uml}uismo." » {uml}mismo.", {uml}sismo.", {uml}ismo."
{uml}sismos." » {uml}mismos."

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