Yes, it has always been fine to add multiple documents to a single IndexWriter via multiple threads (at least back to 1.4 when I started hacking on Lucene). -Yonik --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
