Perhaps you should try some spelling variations:
multiling » multilingues
multilingue » multilinguesue
multilingueues » multilinguesueues, multilingues, multiligues
{uml}ismo." » {uml}mismo.", {uml}sismo.", {uml}istmo."
{uml}sismos." » {uml}smismos.", {uml}ssismos.", {uml}sistmos."
{uml}mismos." » {uml}mmismos.", {uml}msismos.", {uml}mistmos.", {uml}mismo."

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 multilingueues)({uml}ismo." OR ({uml}sismos." OR {uml}mismos."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((multiling or multilingue) or multilingueues)({uml}ismo.\" OR ({uml}sismos.\" OR {uml}mismos.\"))".
• Removing quotes may allow a broader search: ((multiling or multilingue) or multilingueues)({uml}ismo. OR ({uml}sismos. OR {uml}mismos. )).
• Adding a wildcard symbol may retrieve word variants: "((multiling or multilingue) or multilingueues)({uml}ismo." OR ({uml}sismos." OR {uml}mismos."))*.
