Restoring a corrupt index
Dear fellow Luceners,
I had a disk failure while indexing and am now unable to get ANY of the
documents stored in my index. I am interested in restoring as many
documents as possible from what is a mostly complete index.
Is there something I can alter by hand to at least get most of the data
back? I am getting an EOF error on the file/segment _cu0v which was
presumably the file that was being written when the index crashed. Is there
a reference to that file in segments that I could edit out??
I have included what I hope is useful information below.
Thank you,
Will

This is the call-stack from an optimize call
IndexWriter writer = new IndexWriter(path, new
StandardAnalyzer(), false);
------> writer.optimize();
logger.debug(writer.docCount() + "");
writer.close();
