Googling around for "fieldNorm == 0" brought me to this post that also involved Nutch several years ago, it might be relavant to you:
http://mail-archives.apache.org/mod_mbox/lucene-solr-user/201011.mbox/%3c201011031930.05980.markus.jel...@openindex.io%3E My only thought is that if your fields are abnormally large, then I wonder if its possible to encounter a rather large floating point underflow ( http://en.wikipedia.org/wiki/Arithmetic_underflow). Lucene's very low precision 8-bit floats used to encode norms would exacerbate this. -Doug On Mon, Apr 21, 2014 at 12:22 AM, Arun V C. <arun...@eteamindia.com> wrote: > Thank you very much for the reply, > > Please find attached schema.xml and solrconfig.xml, most it is default. > > > -----Original Message----- > From: Doug Turnbull [mailto:dturnb...@opensourceconnections.com] > Sent: Sunday, April 20, 2014 9:42 PM > To: Arun V C.; solr-user@lucene.apache.org > Subject: RE: Score is always zero > > Arun, your field norms are all suspiciously 0, which.multiplied through > the scoring calculation causes the overall score to be 0. > > Are you using anything other than the default similarity?
