Hi Gabriele, If you have a copy of Lucene in Action 2, that may be the easiest place to read up on stopwords. In short, when something is a stopword, it is just that stopword that gets removed and thus not indexed and thus when you search for it, it will not find a document that originally had that word.
Otis P.S. Yes, reply works better. :) ---- Sematext :: http://sematext.com/ :: Solr - Lucene - Nutch Lucene ecosystem search :: http://search-lucene.com/ >________________________________ >From: Gabriele Kahlout <gabri...@mysimpatico.com> >To: solr-user@lucene.apache.org; Otis Gospodnetic <otis_gospodne...@yahoo.com> >Sent: Tuesday, September 27, 2011 6:43 PM >Subject: Re: How to reserve ids? > > >Otis, > >I'm following up on this as solving my problem though the stopwords mechanism >would be great.
