Hi Sonia, I agree with Erick here. Negative scores don't make sense and Lucene never computes scores for documents that don't match a query.
E. g. if your query is: "term1 OR term2", then every document that contains term1 or term2 or both will have a score greater than 0. But if two docs don't contain either of the two terms, why should one of them have a lower score than the other one? Both would have 0. -Michael HAIDUC SONIA wrote: > I am trying to order all the documents in the index according to their > similarity to a given query.
