As time passes, you might need to optimize or rebuild your Lucene search index. High availability Lucene indexes allow you to take one Lucene node out of service for required maintenance while the other Lucene node continues to operate.
For more information about how to perform needed maintenance on the Lucene search index, see Managing the Lucene Index
in the Novell Filr 1.1 Administration Guide.
For information about an example setup, see Completing the Cluster Setup
in the Planning and Deployment Best Practices Guide.
