Hi Pradeep, There are a couple of uses cases I can think of in my own applications.
Also, inquiries like these made me believe there are also others that may have similar needs: http://lucene.472066.n3.nabble.com/bitwise-comparer-td485697.html http://lucene.472066.n3.nabble.com/Query-with-bitwise-operation-td495193.html http://lucene.472066.n3.nabble.com/Solr-and-bitwise-comparaison-td504367.html http://lucene.472066.n3.nabble.com/Best-way-to-handle-bitfields-in-solr-td473621.html I hope that answers your question.
