Can I search tweets using keyword and certain user range as filter?



Dear all, I’m a Prof. in Communication area. My recent research is related to Twitter. I’d like to collect tweets using several key words on the accounts of some public twitters’ followers over a certain period of time.

I’ll be very grateful if you could let me know whether this is technically feasible and if so whether you could provide me with some instructions or some doc links. Thank you in advance and I’m looking forward to hearing from you.
