KeywordRepeatFilterFactory

java.lang.Object
- org.apache.lucene.analysis.util.AbstractAnalysisFactory
- - 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.

Since:
