Increase the minMergeDocs and use the compact file format when creating your index.

Subject: when indexing, java.io.FileNotFoundException


Hi,
I am getting this exception now and then when I am indexing content.
It doesn't always happen. But when it happens, I have to delete the
index and start over again.
This is a serious problem for us.

In this email, Doug was say it has something to do with win32's lack of
atomic renaming.

But how can I prevent this?
