Ok, as I understand I need a more up to date version. So far I'm playing around 
the 1_33 release because that is the latest release for Mediawiki / Wikibase.

You raised the right issue : I've checked in chrome's console, and the XHR sent 
is : "?action=opensearch&...". Do you know how can I set the search box to use 
the wbsearchentities API ? I don't remember seeing this option or disabling it 
anywhere.
