If boosting is applied to all documents, then why result order is changing? Sometimes documents without a value can show-up before because there are other factors that contribute score calculation. http://lucene.apache.org/core/3_6_0/api/all/org/apache/lucene/search/Similarity.html If you add &debugQuery=on, you can see detailed explanation about how calculation is done.
