That is only a thought, because I haven't upgraded to 4.0 yet. -Paul > -----Original Message----- > From: Igal Sapir [mailto:i...@getrailo.org] > Sent: Wednesday, January 09, 2013 11:42 AM > To: java-user@lucene.apache.org > Subject: Re: Upgrade Lucene to latest version (4.0) from 2.4.0 > > I can not elaborate much myself add there are many changes and I'm not an > expert on License. > > I can tell you though that many signatures have changed as well as package > names. > > There were many API changes even between 3.6 and 4.0 > > -- > typos, misspels, and other weird words brought to you courtesy of my mobile > device. > On Jan 9, 2013 11:21 AM, "saisantoshi" <saisantosh...@gmail.com> wrote: > > > Thanks.
