I'm sorry for delay reply. I couldn't get access to the internet these days for some reason. I do apologize for my rough work and very bad readability. I posted it in a hurry and I didn't mean to cause the reader so much inconvenience. I'll NEVER make such a mistake again. Currently, I've made some optimization Tom advised and removed the macro HASHVALUE_ONLY. And I'm working on fixing the problem that it crashed in large data set. I'll post a new patch later. Thank you for all your advice and test.
