The Lucene FAQ ( specifically warns
against using remote file systems. Depending on what you mean by "network-accessible", it
could be a lot slower. You (probably) want something of the form: the data is stored locally,
but is updated periodically from a remote location. The simplest thing is a scheduled task
which just copies over the new index every day at midnight. 

Even with an ideal filesystem, you're going to have to deal with paying an additional warmup
penalty that you wouldn't get in an NRT configuration.

Another thing to note is that, while it's very easy to have multiple readers, it is really
hard to have multiple IndexWriters. We just have one writer, and deal with the fact that it's
not highly available. 

Hope this helps,

Subject: [Lucene.Net] Server farm sharing Lucene

How have folks gone about setting up Lucene in a server farm?  Just a network-accessible
shared directory?
