Great, thanks for your help, I understand things quickly but I need lots of explanation .. ;-) For who is interested .. I was using : int id = hits.doc(i); instead of : int id = hits.id(i); Tchõ Bertrand On Jan 13, 2005, at 10:17 AM, Bertrand VENZAL wrote: > > > > Hi, > > Thanks for your quick answer, I understood wot u meant by using the > indexSearcher to get the termFreqVector.

Yes, the Document id (the one Lucene uses) is not to be relied on long-term. But, in the example you'd get it from Hits immediately after a search, and thus it would be accurate and usable. You do not need to store any the id during indexing - Lucene maintains it and gives it to you from Hits.
