Hi Rajesh, I suspect it is due to the queryNorm(q). But it is weird that relative order is different in your example.
"queryNorm(q) is a normalizing factor used to make scores between queries comparable. This factor does not affect document ranking (since all ranked documents are multiplied by the same factor), but rather just attempts to make scores from different queries (or even different indexes) comparable."

My debug scores seem to be what I expect, but the actual scores applied by Solr are sometimes divided by an integer. I raised the same question in this email distribution about a week ago, but haven't yet found a solution. There's also a StackOverflow question I created here: http://stackoverflow.com/questions/35921106/how-and-why-do-solr-explain-values-differ-from-the-solr-score Can you verify whether all of your affected scores are (1/N)*score? I think N seems to be the number of OR elements in the query. For example, your case below has debug_score/score = 1.2517526/0.41725087 = 3 Thanks, -Rick ---------------------------------------- > From: r...@cebglobal.com > To: solr-user@lucene.apache.org > Subject: RE: Explain score is different from score > Date: Fri, 18 Mar 2016 13:29:14 +0000 > > Can someone help? > > > > > Corporate Executive Board India Private Limited.
