You should ensure that your Lucene node servers remain in sync with each other. Whenever a Lucene node is down for a relatively short period of time (no more than one or two days), you can synchronize it with other Lucene nodes whose index files are up-to-date.
Ensure that the out-of-date Lucene node is running reliably again.
Log in to the Vibe site as the Vibe administrator.
Click your linked name in the upper right corner of the page, then click the Administration Console icon .
Under Search Index, click Nodes.
To repair the out-of-date Lucene node, select Apply Deferred Update Log Records to the Index, then click Apply.
The Deferred Update Log options disappear if the update is successful. If for some reason the deferred update log records cannot be applied to the index, you can rebuild the index, as described in Rebuilding the Lucene Index
in Site Maintenance
in the OpenText Vibe 4.0.8 Administration Guide.
