Class StempelFilter

  • All Implemented Interfaces:
    Closeable, AutoCloseable

    public final class StempelFilter
    extends TokenFilter
    Transforms the token stream as per the stemming algorithm.

    Note: the input to the stemming filter must already be in lower case, so you will need to use LowerCaseFilter or LowerCaseTokenizer farther down the Tokenizer chain in order for this to work properly!
