Hello All,

Upon reading the article 

http://www.lucidimagination.com/Community/Hear-from-the-Experts/Articles/Scaling-Lucene-and-Solr

I have a question around index replication. 

If the query load is very high and I want multiple severs to be able to
search the index. Can multiple servers share one read-only copy of the
index?

so one server (Master) builds the index and it is stored on a SAN. Then
multiple Slave servers point to the same copy of the data and answer user
queries.

In the replication diagram, I see that the index is being copied on each of
the Slave servers. 

This is not desirable because index is read-only (for the slave servers,
because only master updates the index) and copying of indexes can take very
long (depending on index size) and can unnecessarily waste disk space.
