If you add "debugQuery=true" to your URL request, then you will get a full accounting of how the score was calculated for each document in the results. I think "debug=query" also works. Looking at the source code for DefaultSimilarity is probably also helpful. Here's the javadoc for that class: http://lucene.apache.org/core/5_2_0/core/org/apache/lucene/search/similarities/DefaultSimilarity.html Much more detailed info is available by clicking on the parent class link (TFIDFSimilarity) on this page. Thanks, Shawn
