How to train rasa for multi-purpose?

I am currently using but for FAQ system I want to do something else as is not so familiar for FAQ and user-friendly. I have users with the different-different purpose like some of them want to use it as support, service etc. So how can I train rasa automatically according to user expression?

hi @shivamg068, I think you could have a look at our getting started guide of rasa_nlu. Hope this helps
