Thanks Uwe. This seems to be a handy tool. My problem is I need a better example (tutorial maybe) to show me what are necessary/default filters a SmartChineseAnalyzer or JapaneseAnalyzer needs. In this case, I guess I need a HMMChineseTokenzier and a stop filter but not a porter stem filter. I could give a try later but a tutorial would be nice. Thanks for the suggestion though.
