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,
IOException, SQLException {
writer.commit();
if(indexReader!=null)
indexReader.reopen();
}
What do you mean by real-time reader?
Thanks.
