> That's all because of org.apache.lucene.analysis.cn.smart.hhmm.SegGraph's makeIndex()
method:
>   public List<SegToken> makeIndex() {
>     List<SegToken> result = new ArrayList<SegToken>();
>     int s = -1, count = 0, size = tokenListTable.size();
>     List<SegToken> tokenList;
>     short index = 0;
>     while (count < size) {
>       if (isStartExist(s)) {
>         tokenList = tokenListTable.get(s);
>         for (SegToken st : tokenList) {
>           st.index = index;
>           result.add(st);
>           index++;
>         }
>         count++;
>       }
>       s++;
>     }
>     return result;
>   }
> here 'short index = 0;' should be 'int index = 0;'. And that's reported here http://code.google.com/p/imdict-chinese-analyzer/issues/detail?id=2
and http://code.google.com/p/imdict-chinese-analyzer/issues/detail?id=11, the author XiaoPingGao
have already fixed this bug:http://code.google.com/p/imdict-chinese-analyzer/source/browse/trunk/src/org/apache/lucene/analysis/cn/smart/hhmm/SegGraph.java
