Jack due to 'some' reason my nutch is returning me index time boost =0.0 and just for a moment suppose that nutch is and will always return boost =0.
Now my simple question was why Solr is showing me document's score = 0 ? Why is it depending upon index time boost value ? Why or how to make Solr to only calculate the score value on TF-IDF ?
