    - #### LimitTokenCountAnalyzer

          public LimitTokenCountAnalyzer(Analyzer delegate,
                                         int maxTokenCount)

      Build an analyzer that limits the maximum number of tokens per field. This analyzer will not consume any tokens beyond the maxTokenCount limit
      See Also:
        `LimitTokenCountAnalyzer(Analyzer,int,boolean)`

    - #### LimitTokenCountAnalyzer

          public LimitTokenCountAnalyzer(Analyzer delegate,
                                         int maxTokenCount,
                                         boolean consumeAllTokens)

      Build an analyzer that limits the maximum number of tokens per field.
      Parameters:
        `delegate` - the analyzer to wrap
        `maxTokenCount` - max number of tokens to produce
        `consumeAllTokens` - whether all tokens from the delegate should be consumed even if maxTokenCount is reached.
