28.3 Optimizing the Lucene Index

If you notice that search performance in Vibe is becoming slower over time, you might want to optimize your Lucene index.

For a medium to large Vibe system, it is recommended that you run the optimization once a week. You should run the optimization during off hours or on weekends when the Vibe 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Optimizing the Lucene index does not repair a damaged or out-of-date index. To repair a damaged or out-of-date index, you must rebuild the index, as described in Rebuilding the Lucene Index.
