Opening the url with the language of the previously opened community's language

Hi, 

We are using below urls to call search results, however the url opens the search page with the language of the last browser that is called.

To exemplify; I open community.sony.co.uk, then in another browser call the below url. The search result page is in English, although the domain is sony.de and shall be german. 

http://community.sony.de/t5/forums/searchpage/tab/message?location=category%3Anl&q=october&phrase=october&advanced=true&search_type=message&filter=labels%2Clocation

Is there a language parameter we can add to the url to call the search result pages in correct language all the time? 

Thanks, Zehra
