Perhaps you should try some spelling variations:
multiling » multilingues
multilingue » multilinguesue
multiligues » multilingues, multilingual, multipliquen
{uml}uiso." » {uml}quiso.", {uml}guiso.", {uml}uismo."
{uml}sismo." » {uml}sismos.", {uml}mismo.", {uml}simo.", {uml}smismo.", {uml}sistmo.", {uml}siso."
{uml}ismo." » {uml}mismo.", {uml}istmo.", {uml}iso."

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 multiligues)(({uml}uiso." or {uml}sismo.") or {uml}ismo.")~.
• If you are trying to use Boolean operators, they must be ALL CAPS: "((multiling or multilingue) or multiligues)(({uml}uiso." OR {uml}sismo.") or {uml}ismo.")*.
• Removing quotes may allow a broader search: ((multiling or multilingue) or multiligues)(({uml}uiso. or {uml}sismo. ) or {uml}ismo. )*.
