Thanks for the reply. Hmm, I understand. I know about AnalyzerWrapper, but that is not what I am looking for.
I also know about cloning and overriding. I want my analyzer to behave exactly the same as EnglishAnalyzer and right now I am copying the code from the EnglishAnalyzer to mimic the behavior, which is a dirty solution. Is there any other proper solution(s) to this problem? Thank you.
