On a wiki with language converter enabled, opensearch can try to convert the search keyword to all available variant, and do opensearch with them individually as how OpenSearch does currently, then combine the results and send the user. Some algorithm may be needed to sort the results.
Maybe sorting by title lengths is ok, but what if some of them are equal?
For the default search backend (i.e. ApiQueryAllPages), adding the converttitles parameter to the FauxRequest in PrefixSearch::defaultSearchEgine should suffice, but that won't solve the Wikimedia case.
