public abstract class SimilarityFactory
extends Object

A factory interface for configuring a Similarity in the Solr schema.xml.

Subclasses of SimilarityFactory which are SchemaAware must take responsibility for either consulting the similarities configured on individual field types, or generating appropriate error/warning messages if field type specific similarities exist but are being ignored. The IndexSchema will provide such error checking if a non-SchemaAware instance of SimilarityFactory is used.
