Lucene Corrupt Index Exception
Hi,
We have integrated Lucene with our program and one of the user is facing the
Lucene Corrupt Index Exception. When I ran the CheckIndex command, I got the
following result...
followed by...
Any idea what could have caused this index corruption? I will fix the index
using the CheckIndex command, but the question is why did the index get
corrupted in the first place.
Thanks!

Hmm I still don't see the details in your email, but clicking through
to Nabble I could see them:

WARNING: 1 broken segments (containing 19 documents) detected
WARNING: 19 documents will be lost
Somehow the deletions file (_1bs4_7.del) thinks there are 0 deleted
docs in this segment (which is weird: if that were true then this file
would not have been written), vs the 7 deleted docs recorded in the
segments file. If you had passed -fix to CheckIndex it would drop
that one segment (and all docs it contains) from the index.
Did anything unusual happen during indexing?
Are you using IndexReader.undeleteAll?
Also, 3.1.0 is quite old now ... it could be you're hitting a bug that
was already fixed in later versions.

Hi, I only see whitespace under "following result..." and "followed by...".
Were there any interesting exceptions during indexing?
