Hi Rupert, Thanks for the informative reply. I was able to specify an empty String as the namespace prefix namespaceprefix.mapping file. Exactly as you mentioned, indexing started with no loggings for quite some time. Then the process finish without indexing a single entity.
I used all the default configuration files created by the init process. I'm trying to build a freebase index for multilingual FST linking. I would much appreciate if you can point me to resource where I can get the information to correctly configure the properties files. Thanks, Amindri
