Answer 1

writer = new IndexWriter(DIR, new StandardAnalyzer(), false);
writer = new IndexWriter(DIR, new StandardAnalyzer(), true);
在索引告侍没有建立做友姿前，使用增量索引时，会发生这个异常
在纯绝索引建立时使用writer = new IndexWriter(DIR, new StandardAnalyzer(), true);
以后使用writer = new IndexWriter(DIR, new StandardAnalyzer(), false);
