So, by using backwards codec jar : Lucene 6.6.0 is now using older codec that comes with it, right? Then, the latest codec is enforced to use by reindexing the data with new Lucene 6.6.0 (due to switching from 6.1.0), right?
Thus, i did not need to rerun indexing because of use of backwards codecs jar. However if i reindex data with Lucene 6.6.0 then latest codec would be used. i will try this.
