I think you can reuse them. Fields should he handled/analyzed sequentially. I
reuse them for some stuff on Simpy.com.
But you may want to clean up that try/catch. Instead of catching the
IOException, you may want to use !IndexReader.indexExists(...) in place of that
boolean param to IndexWriter ctor.

expected....
Hey Erik,
Will do. May I ask why? Out of curiousity.
Thanks,
