Class KeywordRepeatFilterFactory

java.lang.Object

      org.apache.lucene.analysis.util.TokenFilterFactory
          org.apache.lucene.analysis.miscellaneous.KeywordRepeatFilterFactory

public final class KeywordRepeatFilterFactory
extends TokenFilterFactory

Factory for KeywordRepeatFilter. Since KeywordRepeatFilter emits two tokens for every input token, and any tokens that aren't transformed later in the analysis chain will be in the document twice. Therefore, consider adding RemoveDuplicatesTokenFilterFactory later in the analysis chain.
