Hi Jack, Thanks a lot for your response.
I agree the question is too much into Lucene which is outside the scope of Solr. However, for those of you who is interested in understanding the Solr Index more, here are a few resources to help: (1) Luke <https://github.com/DmitryKey/luke>: a local application that help you inspect Lucene indexes. (2) SimpleTextCodec <http://datafireball.com/2016/03/07/lucene-simpletextcodec/>: it is not that easily to deserialize Lucene indexes however, you can change the default codec to be SimpleTextCodec and that will help you understand how the index/search part much better.
