Interface LuceneFacetHelper

All Superinterfaces:

BusinessObject, BusinessProcessor

All Known Implementing Classes:

BasicLuceneFacetHelper

public interface LuceneFacetHelper
extends BusinessProcessor

Interface for classes that search on the Lucene index for facets. When the application needs to create an instance that implements LuceneFacetSearcher, BusinessObjectFactory finds the name of the Java class to instantiate from the "luceneFacetSearcherImplementer" setting in the appComponents.properties file.

The default "luceneFacetHelperImplementer" is BasicLuceneFacetHelper.
