Class SolrStopwordsCarrot2LexicalDataFactory

java.lang.Object

org.apache.solr.handler.clustering.carrot2.SolrStopwordsCarrot2LexicalDataFactory

All Implemented Interfaces:

org.carrot2.text.linguistic.ILexicalDataFactory

@Bindable
public class SolrStopwordsCarrot2LexicalDataFactory
extends Object
implements org.carrot2.text.linguistic.ILexicalDataFactory

An implementation of Carrot2's ILexicalDataFactory that adds stop words from a field's StopFilter to the default stop words used in Carrot2, for all languages Carrot2 supports. Completely replacing Carrot2 stop words with Solr's wouldn't make much sense because clustering needs more aggressive stop words removal. In other words, if something is a stop word during indexing, then it should also be a stop word during clustering, but not the other way round.

WARNING: This API is experimental and might change in incompatible ways in the next release.
