17.1 Optimizing the Lucene Index to Improve Search Performance

IMPORTANT:In order for optimization to run, there must be at least 51% free disk space on the Lucene search index appliance.

For a medium to large Filr system, you should run the optimization once a week during off hours or on weekends when the Filr system is not being heavily used.

Optimizing the Lucene index does not repair a damaged or out-of-date index. To repair a damaged or out-of-date index, you must rebuild the index, as described in Rebuilding the Lucene Index.
