Subject Re: "java.lang.IllegalArgumentException: Could not load codec 'Lucene60'. Did you forget to add lucene-backward-codecs.jar?" Error
Date Sun, 29 Jul 2018 20:07:06 GMT
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.
Best
