We have a custom scope implementation and a custom
DirectoryProvider. The custom DirectoryProvider has used a system property
to specify the index base. But now I can remove it and use the default one.
The custom scope implementation were used first to provide
"Conditional Indexing", which is now removed, and it also allows us to
exchange index changes between application nodes using JMS topic and
durable subscribers. Every node has its own index, which it can update
independently of other nodes and posts changes to the index to the JMS
topic. The messages posted to the JMS topic are persistent and contains
unique node id, so that the node may ignore own changes. In our
architecture all nodes are equal. We don't have a master node.

Nice, thanks for the hint!

To be exactly we use Hibernate Search since 2007. :-)

OK, I will do it.
