2.2.3. Rebuilding the Index
The Lucene index can be rebuilt, if required, by reconstructing it from the data store in the cache.
The index must be rebuilt if:
- The definition of what is indexed in the types has changed.
- A parameter affecting how the index is defined, such as the
Analyserchanges. - The index is destroyed or corrupted, possibly due to a system administration error.
To rebuild the index, obtain a reference to the
MassIndexer and start it as follows:
SearchManager searchManager = Search.getSearchManager(cache); searchManager.getMassIndexer().start();
This operation reprocesses all data in the grid, and therefore may take some time.
Rebuilding the index is also available as a JMX operation.
