Hi, Dear Mike:
belows list the report of checkIndex. OS is Fedora Linux.
[oracle@server bin]$ java -classpath ./ org.apache.lucene.index.CheckIndex /data/Index/URL/Generic/
-fix
NOTE: testing will be more thorough if you run java with '-ea:org.apache.lucene...', so assertions
are enabled

主题： Re: A likely bug of TermsPosition.nextPosition
Hmm this could be from a corrupted index.
What version of Lucene? What OS/filesystem?
Can you run CheckIndex and post the output?

success if TermsPosition.next is used. But if TermsPosition.skipTo is used instead of TermsPosition.next,
a java.lang.IllegalArgumentException will be thrown, as bellows.

> In my further study, I found that if docid execeed 1044278, the exception occurs everytime,
for the small ones, the exception never occur. BTW, the total number of documents is about
1344278, and are never deleted.
