Hi Amit;
First of all, I suggest that you should read here:
http://lucene.apache.org/core/4_6_0/core/org/apache/lucene/search/similarities/TFIDFSimilarity.html
to
understand the basics of score calculation of documents.
Thanks;

You might want to look at the Solr Relavancy for the same.
http://wiki.apache.org/solr/SolrRelevancyFAQ
<http://wiki.apache.org/solr/SolrRelevancyFAQ>
Also, it will even better if you look at the link above with outcome you
want to get to, like "Want to know why this document is better than the
other" or "Why the document in my db did not come up?"
