Jeremy,
This might be of help tp you:

And it has a link to explanation of this merge factor parameter...

hi,
Many thanks for your reply, Bernhard.
IOException in index()
This causes the index to be incomplete, and causes further
problems when you try to search using the index.
If I use the Lucene Samples in Cocoon, and index my Cocoon
documentation, I always get this error.
Hm, i once got this kind of error, too,
but i can't remember exactly how i did solve it,
perhaps you must set the mergefactor of lucene differently.
As much as i remember lucene has some options about how many files
are kept opened in case of indexing,
it later merges the indexes files, ....
Ah Ha! I was beginning to think it was some weakness of MacOSX JVM
(or maybe it still is ....).
Have you any idea where this is configured?
Before I started to have the indexing failures, I had another
problem, this time much more difficult to replicate.
About every 10 searches, I would get a "Bad Resource" error from
LuceneGenerator. A simple reload of the page would give me the
search hits I expected.
Can anyone think of a Cocoon cause for these problems, or should I
get onto the Lucene team about them?
Do you have anymore detailed exception stack traces?
I do for the indexing, but not for the intermittent fault, which has
not happened again since the indexing started failing.
Here is the indexing exception report:
