Could you explain a bit more what problem you're trying to solve? The reason I ask is that your question doesn't make sense to me, since I have no idea what you expect by the term "negative score".
My simplistic view has been that all the docs returned via Hits or HitCollector have scores > 0, and all the rest have scores of 0, and this view is supported by the explanation of HitCollector.collect " Called once for every non-zero scoring document, with the document number and its score." You might also get value from this page: http://lucene.apache.org/java/docs/scoring.html#Scoring Best Erick On Nov 19, 2007 11:05 AM, HAIDUC SONIA <[EMAIL PROTECTED]> wrote: > Hi everyone, > > I am trying to obtain the score for each document in the index relative to > a given query.
