Subject Re: lucene index in a cluster.
Date Wed, 17 Oct 2007 22:54:57 GMT
To my experience from a project, using software DBSight, Lucene runs well on
a SAN environment.
No experience of a NFS, but I know many indexing errors caused by NFS. Maybe
the new index delete policy helps in latest version of Lucene.
