Wikimedia Bugzilla is closed!

The user is forced to choose and set only one language even when he is able to use more languages and is active at more Wikipedia projects. If the searched item or property have not its label in the currently selected language, the autocompletion ignores the item or the property. Regrettably, none of language is mandatory in item labels, thus none language (not even English) is usable as the universal language. Properties have their primary label in English (and labels in other languages is mostly missing) - thats forces users to set English as their user language instead of their native language. That all make the work on Wikidata needlessly tiresome. The intention to localize Wikidata harms heavily the universality and internationality of the project. 

Some improvement would be if all searching and autocomplete functions will go through all languages and the user-preferred languages will be preferred in the result list. 

As an example, at Wikimedia Commons, such multilingual fulltext searching (in all language versions of description together) works naturally and usefully. It is necessary especially for proper nouns of people or places, brand names etc.
