I posted errors as comments in the provided code.. Yes seems that the version in the book is a little bit old (as the book was created in 2005)
So is there another manual which I can use to start? (Seems that examples in the book, are carefully chosen for starters, and quite easy to understand) Thanks, Oleg On Tue, Dec 16, 2008 at 12:44 PM, <joseph.syj...@ph.lawson.com> wrote: > > Hi, > What were the errors? > Just a guess ... it may be possible that you are using the wrong lucene > version - the one in the book is not the most updated one avbl today > > *"XP is making a bet.
