If I use IndexReader and IndexWriter class for inserts/updates, then I need to handle the threading issues myself. Is there any other class (even in nightly build) that I can use without having to take care of synchronization.
All this means is your code must ensure only one "writer" (IndexWriter adding docs or IndexReader removing docs) is open at a time. If you fail to do so, then the second "writer" you try to create will throw a "Lock obtain timed out" IOException. Otherwise these classes are fully thread safe. The performance caveat in IndexModifier (that you should batch your deletes and batch your adds) still applies, because you will need to open/close an IndexReader for the former and an IndexWriter for the latter. The Lucene in Action book does a great job describing these concurrency rules. Also, you should first test IndexModifier to be really sure its performance is not sufficient for your needs.
