The Lucene indexes are normally stored in the file system, and can
only be accessed directly on the same host. An alternative would of
course be to access the index over the network like is done with the
MidCOM indexer, but that brings a slight performance overhead and
makes the indexer process a more critical resource.

As I wrote in http://jukkaz.wordpress.com/2006/01/03/implementing-mrfc-0024/,
I've now been experimenting with the various integration mechanisms.
Using a network protocol might actually make sense since none of the
options for linking Lucene directly with midgard-core seem to be very
attractive.
