Subject Re: Please help me to understand debugQuery output
Date Tue, 10 Dec 2013 23:43:21 GMT
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;
Furkan KAMACI
