Do I need to use different algorithm instead of porter stemming..? can you suggest anything in you mind..?

Just a guess: porter stem filter could be "case sensitive" and that may cause the difference. I am pretty sure porter stemming algorithms designed to work on lowercase input. By the way you have two lowercase filters defined in index analyzer.
