最近网站出现了这个问题，，，好郁闷。这是LUCENE的问题。
自己不怎么懂啊。。。只得GOOGLE下啦！

出现以上异常主要有两种原因：
1.系统正在写索引未完成之前，应用程序关闭
解决方法：删除提示的lock文件后重启应用(最好在应用中捕捉到，自动删除)
2.系统中有多个线程或程序在抢用索引
解决方法：增加或改善等待队列机制作，或者出现此错误时先解锁

哎。。。怎么会出现这个问题。。。。看来没希望了。如果要解决这个问题又得叫空间提供商重启服务，那边又会是一堆废话。。。

嘿嘿，自己写个JSP页面，删除了那文件试下了。哈。。。删好，果然，成功了。网站搜索又能使用。哎。。得学习下LUCENE啊。。。不能只知道WHAT不知道HOW啊。
