I understand that there can only be a single active IndexWriter per Directory, but is the IndexWriter multithreaded (it seems to be)?
Do you mean the a IndexWriter works with several threads or is thread-safe? maybe this one helps: http://www.mail-archive.com/lucene-dev@jakarta.apache.org/msg00157.html It would appear that on a multiprocessor box using multiple threads to add
documents from a queue would be much faster (due to the parallel tokenization)?
This is true, you should keep the actual index writer always busy to get the best performance out of the single index writer. There are several approaches around to do that, for ex. you could index your documents mutlithreaded into a RamDir per thread and merge them together after a certain amount of documents. Do I have this correct?
Thanks. Robert
