Perhaps you should try some spelling variations:
multiling » multilingues
multilingue » multilinguesue
{uml}iismo." » {uml}mismo.", {uml}sismo.", {uml}itsmo.", {uml}imismo.", {uml}isismo.", {uml}iistmo."
{uml}ismo." » {uml}mismo.", {uml}sismo.", {uml}istmo."
{uml}omiso." » {uml}comiso."
{uml}sistmo." » {uml}sismo.", {uml}istmo.", {uml}sisto."

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)({uml}iismo." or (({uml}ismo." or {uml}omiso.") or {uml}sistmo."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: "(multiling OR multilingue)({uml}iismo." or (({uml}ismo." OR {uml}omiso.") or {uml}sistmo.")).
• Removing quotes may allow a broader search: (multiling or multilingue)({uml}iismo. or (({uml}ismo. or {uml}omiso. ) or {uml}sistmo. )).
• Adding a wildcard symbol may retrieve word variants: "(multiling or multilingue)({uml}iismo." or (({uml}ismo." or {uml}omiso.") or {uml}sistmo."))*.
