Subject scores are the same for many diferent documents
Date Wed, 17 Feb 2010 12:35:25 GMT

Hey there,
I see that when solr gives me back the scores in the response it are the
same for many different documents.

I have build a simple index for testing purposes with just documents with
one field indexed with standard analyzer and containing pices of text.
I have done the same with a self coded simple lucene indexer.

Quering to the solr index with qt=standard&q=title:laptop will give me back
documents, some of them exactly with the same score.
Quering to the lucene index (with a simple self coded search app) with
title:laptop will give me back no equal scores.

When building solr index I have tryied both omitNorms=true and
omitNorms=false. It will give me different scores but in both cases there
are some equal scores.

I am testing this because I have a Solr component with a
FieldComparatorSource wich uses the scores and other external factors for
the sorting. Having same score for different documents combined with
external factors may give me back results in unexpected undesired order
