Dear Shai, I only made the mistake by using the same directory for both IndexWriter and FacetWriter. Now it is working fine .Thank you :)
Could you please tell me if there is any major performance difference in using *3.6 and 4.x* *Facet *library?. Since I use the Lucene 3.6 version, I am using Facet library also the same version. Kindly guide me to use the best and the working one. :) Thank you :) Thanks and Regards, Jebarlin Robertson.R On Fri, Feb 7, 2014 at 12:41 PM, Jebarlin Robertson <jebar...@gmail.com>wrote: > Dear Shai, > > Thank you for your reply. > > Actually I am using Lucene3.6 in Android.
