Subject Re: Lucene 2.9.0 leaves too many .cfs files open, causing too many files open java error.
Date Sun, 18 Oct 2009 17:47:36 GMT

I commit the IndexWriter every 200 documents in a batch as follows and you
can see that I reopened the reader after the commit.

private void commit(IndexWriter writer) throws CorruptIndexException {
		writer.commit();
		if(indexReader!=null)
			indexReader.reopen();
}

What do you mean by real-time reader?

Thanks.
