Re: Handling multiple locale

Hi Michael, Thanks for the reply. Yeah, that's one brute force way of doing it. But then one has to find all the locales in the system. Is there any other way ? Regards. -- View this message in context: http://lucene.472066.n3.nabble.com/Handling-multiple-locale-tp4297805p4297948.html Sent
