    Description

      The "Smart" Simplified Chinese toolkit in lucene/analysis/smartcn does not work in some edge cases. It fails to split certain words which were not part of the dictionary or training corpus.

      This patch supplies a bigramming class to handle these occasional mistakes. The algorithm creates bigrams out of all "words" longer than two ideograms.
