Class AggressiveOptimizer

java.lang.Object
  org.compass.core.lucene.engine.optimizer.AbstractOptimizer
      org.compass.core.lucene.engine.optimizer.AbstractIndexInfoOptimizer
          org.compass.core.lucene.engine.optimizer.AggressiveOptimizer

All Implemented Interfaces:

CompassConfigurable, SearchEngineOptimizer, LuceneSearchEngineOptimizer

public class AggressiveOptimizer
extends AbstractIndexInfoOptimizer
implements CompassConfigurable

Agressive optimzer optimizes the index down to a single segment once it has more that the configured merge factor segments. The merge factor can be configured using LuceneEnvironment.Optimizer.Aggressive.MERGE_FACTOR (which deftauls to 10).

Forced optimization will optimize the index regardless of the number of segments.
