Hi,
I am relativly new to Lucene and I am trying to index
the docs, as and when they are uploaded to the system,
by calling the following code: I keep getting 'segment
file not found error (thru debugger), when I was
expecting it to create those index files.
Can anybody look into the following code and tell me
what is my mistake/errors? Any help on this is
appreciated. Thanks,
Vinu
